Er:YAP

Er: YAP has a large emission cross section of 3μm, which is three times larger than Er: YAG. High doped Er: YAP can emit 2.73 µ m laser, and low doped Er: YAP Crystal can emit 1.66 µ m laser. The emission and excitation spectra of Er: YAP Crystal show that there is a wide emission band in the safety region of human eyes, and its peak is around 1545nm and 1608nm. The pump band is suitable for common 800nm and 970nm diode lasers, which shows that Yap is a 1.5 μm candidate crystals for diode pumped lasers within the safety range of human eyes.Compared with YAG, yttrium perovskite aluminum (Yap) is expected to become a matrix material for effective laser emission because of its high thermal conductivity (~ 13.3 w M-1 k-1), good mechanical properties and low photon energy. Moreover, Er: YAP is one of the most promising laser materials, which can provide high-power mid infrared coherent beams.Higher thermal conductivity, Lower phonon energy, Good mechanical properties, Abundant energy level structure, High doping concentration.

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
