For the crystal color white series photonic chips. The white series laser pointer photonic wafer is a kind of nonlinear crystal. It is the product of the cross-combination of our team's technologies in the fields of micro-nano optics, nonlinear optics, and laser. The reason why the white series photonic wafer can make the laser produce white light is mainly because the interior of the wafer has been modified. After the modification, the wafer interacts with ordinary pulsed lasers to produce white light lasers with various colors and infrared, ultraviolet and other spectral bands. This is a groundbreaking invention for the entire laser field and a very promising photonic wafer material.
At present, the white series of photonic chips have been developed to the second generation of products. The first generation of white laser technology used a mid-infrared femtosecond pulsed laser on the crystal. Then a white light laser is generated. But because the power of the mid-infrared laser is relatively low, the power of the white light laser produced is not high. In order to meet the application of white light lasers in more fields, the total power of white light lasers must be increased. For this reason, Jingzhi Cai successfully developed the second generation white light laser products. Using near-infrared femtosecond pulsed lasers to act on non-linear crystals, resulting in higher power white light lasers. The power is increased from a few milliwatts before to the current one hundred milliwatts.
"The birth of white photonic crystals is the best interpretation of the application of aligned phase matching theory in practice; because we have just started, we have achieved the results of turning theoretical products into commercial products, but we are not satisfied. The continuous research and development of crystals is the top priority of our enterprise, and it will also become the long-term business strategy guidance of our enterprise development. In the future, there will be higher and newer products available. We are confident to send the green laser pointer to the future Outlook.
Observing the stars and other constellations with a green laser pointer is a simple and convenient task. Usually when you need to see a certain star in the night sky, the green laser pointer is enough, and it can also be used to find small points on low clouds. When pointing to stars or other constellations for a large number of people, the low-power green laser pointer does not work. It is a great convenience for astronomers to aim at the target quickly and easily.
