Nd：KGW laser crystal datasheet-Laser-crylink

Nd:KGW crystal is a kind of laser crystal that can realize high concentration doping.Because the crystal can be mixed with high concentrations of Nd ions and has a large emission area, its monopulse and low-repeat laser performance is better than Nd: YAG. The absorption band of Nd: KGW crystal is at 808 nm, which can effectively couple with LD pump source (emitting wavelength is 808 nm) to improve its luminous efficiency. Moreover, its half height and width of 12 nm makes it able to accommodate the drift of LD emission wavelength with temperature, which is conducive to conducting diode pumped KGw laser experiment and device research. Nd:KGW can not only realize free oscillation, Q switching, mode locking operation, but also realize Raman conversion.

Nd:KGW crystal—A crystal can be generated from excited Raman scattering and become a multi-wavelength light source in visible band after frequency doubling.

The Raman characteristics of Nd:KGW crystal depend on its high excited beam cross section, low pumping threshold, high output energy, high conversion efficiency, and two high Raman gain coefficients (768 and 901 cm-1).Since the fundamental frequency light of Raman crystal is 911 nm, 1067 nm and 1351 nm, the red, yellow and blue light of 0.455 um, 0.533 um and 65 um can be produced after frequency multiplication, which can be used in material processing, optical communication, tele-sensing, medicine, environmental monitoring, precision measurement and other fields.

Pockels Cells Crystal

1. Pockels Cells Based on the electro-optic effect , when the applied electric area acts on the Pockels cell crystal ( electro-optic crystal ), the Pockels cell crystal (electro-optic crystal) is like a wave plate whose phase delay is related to the used electric field. The polarization state of the outbound light from the Pockels cell crystal will certainly change so that the strength as well as amplitude of the outbound light from the analyzer are regulated, which is electro-optic inflection, and the modulation tool is called a Pockels cell. 2. Pockels cell crystal The crystals that produce the electro-optical effect are called Pockels cell crystals, that is, electro-optical crystals. They each have their benefits. Presently, the major Pockels cell crystals on the marketplace consist of BBO crystals , DKDP crystals , KTP crystals , as well as LN (LiNbO3) crystals . (1) BBO crystal BBO crystal , additionally called barium metaborate crystal, chemical formula BaB2O4, is an electro-opt

  YCOB nonlinear crystal – Laser Crylink laser crylink Description YCOB crystal is one of the most widely used nonlinear optical crystals. Its nonlinear optical coefficient is equivalent to that of BBO crystal and LBO crystal. The effective frequency multiplication coefficients of the second and third order reach 2, 8 and 1, 4 times of KDP respectively. The YCOB crystal has the following advantages : large aperture, high damage intensity in femtosecond regime,about2000-2500GW/cm2 wide allowable Angle range and allowable temperature range, small dispersion Angle, shorter growth period by Cz method. At the same time, it has stable physical and chemical properties (non-deliquescent) and good machining properties. Therefore, it is considered to have good application prospects of blue-green light and UV band optical frequency multiplier crystal. Feature · Electric resistivity is high · Temperature acceptance is high · Laser induce damage threshold is high · Less anisotropy · Thermal expansi

Neodymium doped yttrium vanadate (Nd: YVO4) is a kind of laser crystal extensively utilized at present. It has superb efficiency as well as is among the major laser crystals for semiconductor pumped solid state lasers today. Nd: YVO4 crystal is a tetragonal crystal, belonging to the uniaxial crystal system, which is composed of doped ion Nd and also laser matrix YVO4. Compared to another frequently utilized Nd: YAG crystal, Nd: YVO4 has the advantage of higher absorption coefficient. In a specific variety of absorption transmission capacity, the absorption effectiveness of Nd: YVO4 is 5 times that of Nd: YAG, the transmission capacity is 2.4-6.3 times that of Nd: YAG, as well as the peak wavelength of the absorption top is reached at concerning 808nm, which has satisfied the requirements of present high-power laser diodes. The boosted sample of Nd: YVO4 at 1064nm and also 1342nm are bigger, and also the boosted random sample of Nd: YAG at 1064nm have to do with 3 times that of Nd: YAG
