Laser Crystal Nd:YAG Overview: Invented in the sixties of the last century, Nd:YAG has been and continue to be the most widely used laser crystal for solid-state crystal material. Its laser parameters are a good compromise between the strengths and weaknesses of its competition. Nd:YAG crystals are used in all types of solid-state lasers. Compared with others laser crystals, its fluorescence lifetime is twice more than Nd:YVO4 , and thermal conductivity is also better.

E-O Crystal LiNbO3 Overview: LiNbO3 crystals are widely used as frequency doubling for wavelengths more than 1μm and optical parametric oscillators (OPOs) pumped at 1064 nm as well as quasi-phase-matched (QPM) devices. Due to their large Electro-Optic and Acousto-Optic coefficients, LiNbO3 crystals are the most commonly used material for pockel cells, Q-switches for Nd:YAG, Nd:YLF, Ti:Sapphire lasers, and phase modulators, waveguide substrates, surface acoustic wave (SAW)

Passive Q-Switch Crystal Cr:YAG Overview: Cr4+:Y3Al5O12 crystal (Cr4+:YAG) is one of the most promising passive Q-switching materials for passively Q-Switching diode pumped or lamped Nd or Yb doped lasers at wavelength from 0.8 to 1.2um. Because of Cr4+:YAG's chemical stability, durability, UV resistance, good thermal conductivity, high damage threshold (> 500 MW/cm ) and easy operation, Cr4+:YAG will replace some traditional switching materials, such as LiF and organic Dye.

Birefringent Crystal Quartz Overview: Single Synthetic Crystal Quartz is grown by hydrothermal method in autoclaves. It has trigonal crystal structure with right-handed or left-handed modification. Quartz crystals have low stress birefringence and high refractive index homogeneity. The optical transmission range of crystal quartz is 0.2-2.5microns. Due to its piezoelectric properties, low thermal expansion, good mechanical parameters and excellent optical characteristics,

Birefringent Crystal MgF2 Overview: Magnesium Fluoride (MgF2) is good birefringent crystal with good transmission over 120-7000nm. It is a hard material which is resistant to thermal and mechanical shock and can be worked according to the highest standards. MgF2 single crystals is a positive birefringent crystal and widely used for Optical prisms, lenses, windows and other optical components. General Specifications Of MgF2: Dimension Tolerance ±0.1mm Optical Axis Orientation

Birefringent Crystal Calcite Overview: Calcite is a negative uniaxial crystal that has high birefringence, wide spectral transmission and availability in reasonably sized rhombs. Although is a fairly soft crystal and is easily scratched, it is an ideal material used as visible and near IR polarizers, such as Glan Thompson, and Glan Taylor, Glan laser polarizer. General Specifications Of Calcite: Dimension Tolerance ±0.1mm Optical Axis Orientation ±0.5deg Surface Quality 20/10

Laser Crystal Nd:YVO4 Overview: Nd:YVO4 crystal is one of the most efficient laser host crystal currently existing for diode laser pumped solid state lasers. Its large stimulated emission cross-section at lasing wavelength, high absorption coefficient and wide absorption bandwidth at pump wavelength, high laser induced damage threshold as well as good physical, optical and mechanical properties make Nd:YVO4 an excellent crystal for high power, stable and cost effective diode

Overview: The diffusion bonded Cr:YAG+Nd:YAG Rod consists of one Nd:YAG crystal and one or two Cr:YAG absorber. They are combined by optical contact method and further bonded under high temperature. The diffusion bonded Cr:YAG+Nd:YAG Rod helps to decrease thermal lens effect considerably in high power solid state Laser. General Specifications Of Diffusion Bonded Nd:YAG + Cr:YAG: Nd:YAG Doping 0.4-1.1% Intrinsic Loss 0.1%cm-1 Scattering Sites invisible, probed with a He-Ne

Laser Crystal Nd:Ce:YAG Overview: Nd:Ce:YAG is an excellent laser material used for no-water cooling and miniature laser systems. The thermal distortion of Nd:Ce:YAG is appreciably less and the output laser energy is greater(30%-50%) than that in Nd:YAG at the same pumping. It is the most ideal laser material for air cooling laser and is also suitable for different modes of operation (pulsed, Q-switched, mode locked) and high-average power lasers.
