"It is well-known that the mature fiber laser pointer is used in industry. It is just the tip of the iceberg for laser applications. At present, the application of laser has been reflected in many fields. White photonic crystals have very powerful functions, how to discover white lasers The application of the white light laser needs to be analyzed. To discuss the future application field of the white light laser, it is necessary to start from analyzing the characteristics of the white light laser generated by the white photonic crystal. "The experts at the meeting analyzed the future application field of the white light laser .
The white light laser produced by the White photonic crystal is different from the white light laser produced by the RGB three-primary-color composite white light laser and the photonic crystal fiber laser. The "laser" produced by the latter is not coherent and should be more attributed to strong pulsed light (IPL). Or in the category of pulsed glare, it cannot be called a real laser. The laser light produced by White photonic crystal is the only white light laser in the world with full coherence, and each spectral line is coherent with each other. Full coherence is an important characteristic of white light laser; this characteristic is currently difficult to produce by other laser light sources. Using this feature, combined with the current traditional laser applications, laser applications can be expanded and improved in related applications. For example, this feature can overcome the traditional laser can only produce a single or narrow-spectrum wide-wavelength laser at a time. White light lasers can produce hundreds at a time. Thousands of broad-spectrum lasers of different wavelengths coherent with each other. It has irreplaceable advantages in lidar and white light holographic imaging.
In addition, as a super continuous, ultra-wideband green laser pointer light source. Combined with lasers, it can also make great achievements in scientific research and laser application system development. Or it will produce applications in new fields. And easily solve the difficult problems encountered in the current traditional laser applications, such as the use of white photonic crystals can generate any wavelength laser characteristics, to obtain traditional lasers can not produce a specific center wavelength laser.
At present, lasers are widely used in the fields of processing, biomedicine, environmental monitoring, defense and military, scientific research, etc. So, what is the application value of white light laser? Professor Li believes: "White light lasers contain visible, infrared, ultraviolet and other spectral bands, so the application will be very broad. For example, white light lasers will play a great role in the field of environmental monitoring, because a white light laser hits it and can Multiple pollutants in the system act simultaneously to produce a wealth of information. All detection can be achieved at once. If you use ordinary monochromatic laser detection, it needs multiple and different color laser detection to get the detection results, and the efficiency is low .
