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.

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
