Saturable absorber Q-switching of Cr:LiCAF, alexandrite, and ruby lasers using the solid-state polymer dye-doped ORMOSIL was demonstrated. Tunable passive Q-switching of Cr:LiCAF laser with a 2-mm-thick HITCI-in-ORMOSIL (doping concentration was 1.24 × 1016 cm-3) was demonstrated with a 36-cm-long laser resonator (output coupler reflectivity was about 95% near 780 nm). A three-plate quartz birefringent filter was used to tune the laser wavelength. The pulse-width and output energy of the Q-switched laser pulse as a function of wavelength are shown. The Q-switched laser output has a shorter pulse duration and higher pulse energy, when the Q-switched laser action occurs near the absorption peak of the dye Q-switch, which is predicted from the theoretical modeling2.
