What is a nonlinear optical crystal?

Nonlinear optical crystals, called NLO crystals, are usually crystals that can bring nonlinear optical effects under the influence of strong light. Nonlinear optical crystal is a new kind of functional material, the core function is to convert the laser wavelength and expand the tunable range of the laser. Nonlinear optical crystals are one of the core materials of lasers, and there are many varieties of products, and new products are still being developed and published, and the downstream can be used in a wide range.

The frequency conversion of nonlinear optical crystals is simply to change the laser wavelength, and the more commonly used frequency conversion is to make the frequency of the output laser a multiple of the input laser. Changing the wavelength of the laser, for our human eyes, is to affect the color of the laser.

Nonlinear optical crystals are one of the most important new functional materials for photoelectric information. There are more than 100 kinds of nonlinear optical crystals, and their development is closely related to the development of laser technology. The wavelength expansion of laser light source depends largely on the frequency conversion ability of nonlinear optical crystals, which is the material condition and source of improving the laser in different bands (different colors), and is widely used in laser storage, laser communication, laser medical treatment, semiconductor micro-machining, optical communication, laser cutting processing, holography, laser nuclear fusion, laser weapons and other fields.

The application of nonlinear optical crystals is "on the hall, under the kitchen", has become an indispensable part of People's Daily life, amazing and cool stage laser, colorful laser music fountain, green laser pointer for lectures and reports. Be everywhere

Nonlinear optical crystals are also essential core materials in high-tech and modern military technology. Nonlinear optical crystals are used in high-tech equipment such as laser weapons, Divine light Engineering and the National Ignition Facility of the United States. Especially in the use of controlled nuclear fusion, KDP(potassium dihydrogen phosphate) crystals have become the only nonlinear optical crystals suitable for inertially confined nuclear fusion, known as "the baby of the country." In addition, nonlinear optical crystals are also "into the sky", RTP(Rubidium titanooxide phosphate) electro-optical crystals and devices as key core components in the United States "Curiosity" Mars exploration rover and its LIGO gravitational wave detection system to obtain applications.
