What is Co: Spinel

Cobalt spinel, chemical formula Co: MgAl2O4, spinel is a hard, secure crystal that brightens well. Cobalt quickly changes magnesium in spinel without the need for added charge-compensating ions. Passive Q-switches or saturable absorbers produce high-power laser pulses without using electro-optic Q-switches, decreasing bundle dimension and getting rid of high-voltage power products.

Co: Spinel passive q-switch crystal

Co: Spinel has actually been shown to be an extremely effective passive Q-switch for giving off 1.2 µm - 1.6 µm lasers. Co2+ activated MgAl2O4 (Co: MALO, Co: back) can be used as a medium for easy Q-switching of lasers operating in the 1.3 - 1.6 µm spectral array. Examples are 1.32 µm and 1.44 µm Nd: YAG lasers, 1.31 µm iodine lasers, and especially 1.54 µm erbium glass lasers. The completely high absorption cross-section of the Co2+ ion and the practical absence of excited-state absorption make this material a very effective passive Q-switch (without the need for intracavity) for various sorts of erbium glass lasers, consisting of diode-pumped integrated circuits. focus). Minimal excited-state absorption causes high-contrast Q-switching procedure with a ratio of preliminary (small-signal) to saturable absorption higher than 10.

Qualities of Co: Spinel.

  • Low optical losses in the wavelength series of 1,3 µm - 1,6 µm.
  • The high laser-induced damage threshold.
  • Application of Co: Spinel.

Shuffle is an easy emitter of passive Q that can be made use of for semiconductor switching security lasers running at the human eye wavelength of 1.5 μm. Because the 1.5 μm transmitter is suitable for the industry at first as a result of the application of the 1.5 μm medium-wavelength waveguide, so in the case of this wavelength, and some delicate eyes are delicate. (Ge as well as InGaAs photodiodes) availability.

Passive Q-switch for Er: Glass @ 1.54 µm.

Benefits of Co: Spinel.

Cobalt-doped magnesium aluminate spinel (Co: MgAl2O4) can generate short nanosecond pulses with high peak power around the eye-safe wavelength of 1.5 μm, making it ideal for telemetry applications. It has the advantages of:

  • high absorption section
  • long life span
  • consistent cobalt distribution
  • absorption transmission capacity

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
