Crystal Parts
Quartz-crystal/fused-silica elements are core optical components of acousto-optic Q-switches (AOQS), serving as the acousto-optic medium. They provide the physical basis for converting electrical energy (RF drive) to acoustic energy (ultrasound) and then optical energy (laser), enabling precise laser control. Following further processing, the devices are mainly used in lasers, lithography, materials processing, surgery and micromachining.

KDP crystal Optical Crystals 100optics
Size（W*H）: 1x1~ customization Length: 0.05~ customization Phase Matching Angle θ,φ: Angel or according to customer request
KDP is potassium dihydrogen phosphate. Potassium dideuterium phosphate (DKDP) has a relatively low nonlinear coefficient, but excellent ultraviolet transmission, a high damage threshold, and high birefringence support widespread industrial use. Both crystals are commonly used for second-, third-, and fourth-harmonic generation of Nd:YAG lasers at room temperature. Their high electro-optic coefficients also support Q-switches and Pockels cells.

LiNbO3 crystal Optical Crystals 100optics
Chemical Formula [Fe-doped Fe:LiNbO3 subsection]: Fe：LiNbO3 Crystal Structure [Fe-doped Fe:LiNbO3 subsection]: Triangular, 3m Density [Fe-doped Fe:LiNbO3 subsection]: 4,64
Lithium niobate (LiNbO3) crystals supplied by Baijing are widely used for frequency doubling at wavelengths of 1000nm or more, optical parametric amplification pumped at 1064nm, and quasi-phase matching. LiNbO3 is also used in optoelectronic modulators, waveguide materials, and Q-switches for Nd:YAG, Nd:YLF, and Ti-doped sapphire lasers. Lithium niobate is among the most commonly used materials for Q-switches, phase modulators, waveguide substrates, and surface-acoustic-wave (SAW) wafers. Iron-doped lithium niobate (LiNbO3, LN) is an excellent photorefractive material with high photorefractive sensitivity, electro-optic coefficient, and diffraction efficiency, plus excellent chemical and mechanical properties. Fe:LiNbO3 crystals are grown by the Cz method, allowing large crystals, with dopant content adjusted to specific application needs. Fe:LiNbO3 is easy to process, inexpensive, and suitable for mass production.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
