The existing laser technology has always had a short board, which can only emit light of a single wavelength or narrow band. How to expand the frequency of the laser forming ultra broadband, super straight, ultraviolet, visible and infrared wavelengths of coherent white light laser, is still a human unfulfilled dream, it is a worldwide problem of science and technology. This is because the laser optics is composed of optical resonator, gain medium and pump source. The wavelength of the laser is determined by the energy level structure of the atoms, molecules or ions in the gain substance.

Because the natural laser crystal material has a great limitation on the gain frequency range and gain bandwidth, the laser can't produce any wavelength of laser.

Will the perfect white laser be created? What changes and developments could it bring to the application of lasers?

1. The sun light

It is known to all that all things grow by the sun, and the sunlight brings light and heat to the earth. The familiar sunlight is a kind of white light, and its spectrum covers ultraviolet - visible - near infrared - mid-infrared bands, as shown in figure 1, In the visible light band (400-700 nm), the radiation energy is strongest, covering seven colors of red, orange, yellow, green and blue, and continuous distribution and transition in the spectrum. Because the sun is white, rainbows are often seen in the sky after rain, or the sunlight passes through a glass prism through seven colors of light (figure 2). This is a common experience in everyday life.

One of the things that people are less familiar with is that sunlight is a completely incoherent light. In terms of spatial coherence, the sunlight cannot be straight and highly divergent. In terms of temporal coherence, there is no phase correlation and locking between different colors of sunlight. So sunlight can only be used to generate energy for heating, water heaters, solar cells and so on.

But the use of modern science and technology, such as the use of sunlight to transmit information, seems to be out of the question.

2. The advantages of light and its application

White light laser light source, short wave laser light sources and continuous laser light compared with the ordinary white light, such as sunlight, incandescent lamp, white LED lamp, etc.), it has the advantages of high brightness, high peak power, wide frequency range etc. In the fields of scientific research, defense military, lighting, communication technology, information technology, industrial production, biomedicine, environmental detection, etc.it got a lot of attention.

White light, as a kind of new laser light source, it has a variety of advantages of good directionality, high energy density, super continuous spectrum, great bandwidth, the center of the flexible wavelength, high degree of coherence time and space. This will greatly expand the function and application scope of laser technology. The white light laser or the solar laser is the completely coherent light, not only the height of the laser beam, but also the very small region. Different color between amplitude and phase locking completely, by regulating the amplitude and phase, it can change the time of laser pulse shape follow one's inclinationsly, and produce very short pulse width (femtosecond and the femtosecond laser pulses. Such a solar laser will have the potential to realize the focus and convergence of light energy in space and time. It releases energy in small areas and very short periods of time to form extremely high instantaneous power density.

Today's society has higher and higher requirements for the quality and safety and reliability of energy and power supply. The traditional large-grid power supply method cannot meet this requirement because of its own defects. A new type of power grid capable of integrating distributed power generation – micro-grid emerges as the times require. It can save investment, reduce energy consumption, improve system safety and flexibility, and is the future development direction. Capacitance plays an important role as an indispensable energy storage system in the microgrid. As a new type of energy storage device, supercapacitor has become one of the preferred devices for microgrid energy storage with its irreplaceable superiority. The microgrid consists of micro power supplies, loads, energy storage, and energy managers. The form of energy storage in the microgrid is: connected to the DC bus of the micro power supply, the feeder containing the important load or the AC bus of the microgrid. Among them, the first two can be called distributed energy storage, and the last one is called central energy storage. When connected to the grid, the power fluctuations in the microgrid are balanced by the large grid, and the energy storage is in the charging standby state. When the microgrid is switched from grid-connected operation to isolated network operation, the central storage energy is immediately activated to make up for the power shortage. The fluctuation of the load during the running of the microgrid or the fluctuation of the micro power supply can be balanced by the central energy storage or the distributed energy storage. Among them, there are two ways to balance the power fluctuation of the micro power supply, and the distributed energy storage and the micro power supply that needs energy storage are connected to a certain feeding line, or the energy storage is directly connected to the DC bus of the micro power supply.

1) Provide short-term power supply

There are two typical modes of operation in the microgrid: under normal circumstances, the microgrid and the conventional distribution network are connected to the grid, which is called the grid-connected operation mode; when the grid fault is detected or the power quality is not met, the microgrid will be timely The grid is disconnected and operated independently, called the isolated mode. Microgrid often needs to absorb some of the active power from the conventional distribution network. Therefore, when the microgrid is switched from the grid-connected mode to the isolated mode, there will be power shortage. Installing the energy storage device will help the smooth transition of the two modes.

2) Used as an energy buffer

Due to the small scale of the microgrid, the inertia of the system is not large, and the network and load often fluctuate very much, which has an impact on the stable operation of the entire microgrid. We always expect high-efficiency generators (such as fuel cells) in the microgrid to always operate at its rated capacity. However, the load on the microgrid does not remain constant throughout the day. Instead, it fluctuates as the weather changes. In order to meet the peak load supply, peak load adjustment must be carried out using a fuel-and-gas peaking power plant. Due to the high fuel price, the operation cost of this method is too expensive. The supercapacitor energy storage system can effectively solve this problem. It can store the excess power of the power supply when the load is low, and feed back to the micro grid to adjust the power demand when the load is high. The high power density and high energy density of the supercapacitor make it the best choice for handling peak loads, and the use of supercapacitor requires only the storage of energy equivalent to the peak load.

3) Improve the power quality of the microgrid

The energy storage system plays an important role in improving the power quality of the microgrid. Through the inverter control unit, the reactive power and active power provided by the supercapacitor energy storage system to the user and the network can be adjusted, thereby achieving the purpose of improving the power quality. Because supercapacitors can quickly absorb and release high-power electric energy, it is very suitable to be applied to the power quality adjustment device of the micro-grid to solve some transient problems in the system, such as instantaneous power failure and voltage swell caused by system failure. Problems such as voltage dips, etc. At this time, supercapacitors are used to provide fast power buffering, absorbing or supplementing electric energy, and providing active power support for active or reactive power compensation to stabilize and smooth fluctuations in grid voltage.

4) Intelligent distributed grid system supercapacitor is essential

From the perspective of the future development of smart grids, intelligent distributed grid systems will be the mainstream of future grid systems. In order to realize the construction of the intelligent distributed power grid system, it is necessary to have a buffer device such as a distributed energy storage device and a central energy storage device. In the case of unstable energy production processes, a buffer is needed to store energy. In the case where the process of energy generation is stable and the demand is constantly changing, it is also necessary to use an energy storage device. A fuel cell is different from wind or solar energy, and as long as it has fuel, it can continuously output stable electric energy. However, load demand varies greatly over time. If there is no energy storage device, the fuel cell will have to be large to meet the peak energy demand, and the cost is too high. By storing excess energy in the energy storage device, it is possible to provide the required peak energy through the energy storage device in a short time.

In distributed grid systems, the transient impact of power systems is inevitable, and the superior performance of supercapacitors can reduce the impact of transient impact on overall system performance. Therefore, in the future intelligent distributed grid system, the ultracapacitor bank energy storage system is indispensable.
