Product Details
Cr4:YAG Passive Q-Switch Crystals
Cr4+:YAG crystal can be used not only as Q-switch but also as gain
medium because of its excellent physicochemical properties. The
Q-switch operation of pulse and CW Nd:YAG lasers has been realized
by using Cr4+:YAG as Q-switch, and the CW tunable and
self-mode-locked operation has also been realized by using CR4 +:
YAG as gain medium. Compared with the traditional saturable
absorber, Cr: YAG is superior to the traditional saturable absorber
in many aspects. The doping concentration of Cr4+ ion in Cr4+:YAG
is as high as 1018 cm-3, which can effectively reduce the size of passive Q-switch elements. It is beneficial to
achieve high optical conversion efficiency, integration, and
compact passive Q-switch laser
