List of Common Nonlinear Crystal

This article introduces the types, characteristics and applications of common nonlinear crystals.

Introduction of Common Nonlinear Crystals:

The emergence of lasers makes the practical application of nonlinear optical effects possible, and the nonlinear effects are also affected by the laser intensity density. The application of nonlinear optical technology has broadened the scope of laser spectrum, thus becoming a new acquisition method of wavelength laser. To achieve nonlinear optical effects, there must be available nonlinear media that can achieve phase matching of light waves.

With the development of laser technology, nonlinear media has also been developed by leaps and bounds. The development trend of nonlinear crystals is very good, and it is highly valued by the country. According to two commonly used phase matching techniques, birefringence phase matching (BPM) and quasi-phase matching (QPM), media can be divided into nonlinear crystals and periodically polarized crystals. Periodically polarized crystals are periodic structures prepared in nonlinear crystals.

There are hundreds of existing nonlinear crystals, the common ones are lithium niobate (LiNbO3—LN), lithium tantalate (LiTaO3—LT), potassium dihydrogen phosphate (KH2PO4—KDP), potassium dideuterium phosphate (KD2PO4—DKDP) ), lithium iodate (LiIO3—LI), potassium titanyl phosphate (KTiOPO4—KTP), barium metaborate (BaB2O4—BBO), lithium triborate (LiB3O5—LBO), potassium niobate (KNbO3—KN), cesium borate (CSB3O5—CBO), Lithium Cesium Borate (LiCSB6O10—CLBO), Potassium Beryllium Fluoborate (KBe2BO3F2—KBBF), Sulfur Silver Gallium (AgGaS2—AGS), Selenium Gallium Silver (AgGaSe2—AGSe), Arsenic Cadmium Germanium (CdGeAs—CGA) ), cadmium selenide CdSe, gallium selenide GaSe, phosphorus germanium zinc (ZnGeP2—ZGP), etc., are widely used in laser frequency doubling, sum frequency, difference frequency, optical parametric amplification, electro-optic modulation, electro-optic deflection, etc.

Application of Structured light projection

Structured light projection (SLP) is a non-contact optical metrology method which can measure to the micron scale. The technique involves projecting a known light irradiance pattern onto the surface under test, which then scatters the light creating a 3D image on the surface. The scattered light is recorded by one or more cameras and the scattered pattern is compared to the modeled projected pattern to determine the surface profile.  For a test surface to be measurable with the SLP technique, it must be a scattering surface over the spectrum of light that is projected on to it. Typically, visible light is used for a SLP device, as the light sources and projection mechanisms are more straightforward to achieve, although another wavelength can be used when necessary. Figure below demonstrates a projected fringe pattern that was captured by a camera, and the corresponding surface that was calculated. Surface height accuracy The surface height features that are measurable by the SLP te...

What is Reflective Coatings?

Image
A very important coating is a reflective version that produces mirrors, coated on the front or back transparent optical material or on the front surface of metallic substrates. This kind of coating reflects a high amount of energy (light in the visible range), which is important for its intended use. As the AR coatings, reflective coatings are also designed for different regions of the spectrum. Aluminum is the most common metallic coating material. Table below shows different kinds of coating materials and the percentage of reflection in different wavelengths. The other type of optical coating used for reflection purposes is the dielectric coating, which uses thin layers of transparent dielectric materials with different refractive indices (e.g., magnesium fluoride or calcium fluoride) and various metal oxides that are deposited onto the optical substrate.

Applications of Machine vision

Image
Machine vision is a very wide area, encompassing practically any system that uses a camera and processing unit to perform an inspection or measurement task. The hardware is typically off-the-shelf components (e.g., telecentric camera) with potentially custom software written to control the devices. The systems help automate processes, speed up manufacturing, and increase yield by replacing a task done by a human that can fatigue and make mistakes. Surface defect inspection Machine vision systems have become widely used in production environments for their automation of an operator’s manual inspection process. Such systems can be used to quantify the geometric dimensions of mechanical features [12]. More recently, machine vision has been applied to the assessment of optical surface quality (scratch dig), typically a task performed by an expert operator. The automation of surface quality inspection affords a repeatable and standardized assessment at the cost of single-purpose systems...
