Times to learn the Pockels Cells

 By applying electric field control to the electro-optic crystal, the refractive index of the electro-optic crystal in a certain direction can be changed, so that the Pockel unit of the electro-optic modulator can be used as a variable half wave plate to change the polarization state. The wave Kerr unit of the electro-optic modulator is placed between two vertical polarizers to realize light intensity modulation. Electro optic effect can be divided into transverse electro-optic effect and longitudinal electro-optic effect. In the transverse electro-optic effect, the propagation direction of light is perpendicular to the electric field, while in the longitudinal electro-optic effect, the propagation direction of light is parallel to the electric field.

Crylink's Pockels battery uses a protective window with high-quality AR coating to ensure high transmission rate and prolong the service life of the equipment.

The half wave voltage of longitudinal electro-optic effect is independent of crystal size, so it is difficult to realize high-frequency electro-optic modulation. The working principle of BBO Pockels battery is based on transverse electro-optic effect. Changing the size of BBO crystal can reduce the half wave voltage. Crylink can provide BBO Pockels batteries with different apertures and lengths, which can adapt to different environments. Due to its low ringing effect and high laser damage threshold, the maximum frequency of crylink's BBO Pockels battery can reach 1MHz.

Co:spinel Q-Switch crystal Cobalt-doped magnesium aluminate spinel (Co:MgAl 2 O 4 ) allow the generation of short nanosecond pulse with high peak power around the eye-safe wavelength of 1.5um,perfect for telemetry applications. The absorption spectrum of Co 2+ -doped MgAl 2 O 4  exhibited a broad absorption band in the wavelength range of 1200–1600 nm, which indicated that Co 2+  ions substituted for the tetrahedrally coordinated Mg 2+  ions in the MgAl 2 O 4  lattice. Passive Q-switching of solid-state lasers with solid-state saturable absorbers is a very attractive Q-switching technique because it allows to develop compact and low cost laser sources of nano and sub nanosecond pulses far various applications Co spinel——saturable absorbers for the passive Q-switching of solid-state lasers operating at eye-safe wavelength of 1.5 μm Lasers emitting at 1.5µm are of great interest for several industrial applications. This interest is, first of all, due to eye-safety of 1....

Nd: YAG principle

Nd: YAG crystal product, likewise called neodymium-doped yttrium aluminium garnet crystal, is a sort of laser tool crystal with good thorough efficiency for solid-state laser. YAG has been and will continue to be the extra widely utilized laser crystal; whether strong state or light pump, CW or pulse, it has an one-of-a-kind mix of qualities conducive to laser operation. Nd: YAG pump tube of using triggered compounds crystal generally krypton light or xenon lamp and pump broadband discharge range is a continual range, however only a few fixed spectrum top absorbed by neodymium ions, so the pump is just a small part of the advantageous spectrum energy is used, and also most are not taken in spectrum power is transformed to heat, so the power utilization proportion is low. The Nd: YAG absorption range ranges from 0730 to 0760 microns and also 0.790 microns to 0.820 microns. The spectrum can be taken in, and after that it will trigger the atom to shift from reduced to higher power degre...

Cr: YAG Crystal

Cr: YAG crystal , also known as chrome-doped yttrium aluminum garnet, is a good passive Q-switching product or saturated absorber. Cr: YAG crystals (passive Q-switches, saturated absorbing) provide high-power laser pulses without the need for electro-optic Q-switches. Such passive Q-switching materials or saturated absorbers can significantly reduce the pulsed laser and stay clear of the high voltage power supply of electro-optic Q-switches. Cr4+: YAG (chromium-doped yttrium light weight aluminum garnet) is widely utilized in Nd: YAG, Nd: Ce: YAG, Nd: YLF, Nd: YVO4, Yb: YAG lasers with wavelengths ranging from 800nm to 1200 nm. Easy Q-switches or saturable absorbers can give high-power laser pulses in the absence of EO Q-switches. Cr4+: YAG crystals are excellent crystals for passive Q-switched diode-pumped or light pumped Nd: YAG, Nd: YLF, Nd: YVO4 or other Nd and also YB-doped lasers at wavelengths ranging from 0.8 to 1.2 µm. Due to its chemical stability, longevity, UV resistance, g...
