Keywords:passive Q-switch, ytterbium

A compact passive Q-switch laser using Yb-doped media has been developed for construct small-size intense infrared laser. Yb:YAG/Cr:YAG composite ceramics make it possible to configure strong laser cavity against optical damage. In experiment 6.3 mJ, 12 ns output laser pulse have been obtained.
