Q-switch

Pulsed laser systems can be achieved with actively or passively Q-switching There are these possibilities to realize those systems: Actively Q-switches systems consist of acousto-optic or electro-optic modulators . For passively Q-switched systems, saturable absorbers as Cr:YAG are used, where this material is utilized for lasers around 1µm wavelength. The most used Q-switched laser systems in this field are Nd:YAG, Nd:YVO4 and Nd:YLF. At higher wavelengths, Er:YAG and Tu doped crystals are used.

Besides single crystal Cr:YAG absorbers, Impex offers integrated types as bonded crystals .
