Characteristics Of Nonlinear Laser Crystals
Total Articles: 98
China is at the international leading level in the research of periodic and quasi-periodic polarization phase matching. Because such quasi-phase matching devices can fully exert the nonlinear optical performance of the [url=https://www.honoroptics.com/high-precision-custom-optical-prism/]purchasing laser grade optical prism[/url], and a crystal can simultaneously perform functions such as frequency multiplication, sum frequency, and parametric oscillation. Therefore, such technologies have important applications in optical communication, laser display, air pollution detection, medicine, and national defense. QPM materials and devices are showing their vitality. Currently more important are PPLN, PPKTP and PPRTA ("PP" is also one of the "quasi-phase matching" notation).
Nonlinear optical crystal in the infrared band
Compared with the nonlinear crystals in the visible and ultraviolet bands, the [url=https://www.honoroptics.com/low-cost-wholesale-optical-waveplate/]zero order/multiple order/achromatic optical waveplate[/url] in the infrared band develops slowly. The main reason is that the optical damage threshold of the existing infrared nonlinear crystal is too low, which directly affects the practical use. Since infrared nonlinear optical crystals have important application prospects in the military, this kind of crystal material has become a key development direction in the field of nonlinear optics.
New photorefractive crystal material
Existing photorefractive materials such as LiNbO3, BaTiO3, etc., when optical information storage applications are used, their photorefractive response speed is not fast enough, and storage noise is still relatively large. The performance of these two aspects cannot be compared with the currently widely used electromagnetic storage. Compared to technology. Therefore, it is necessary to find a new type of photorefractive [url=https://www.honoroptics.com/high-precision-custom-optical-prism/]high precision custom optical prism[/url] with better performance or further improve the modification of the existing photorefractive material.
