Description

Details

Extremely high ground state absorption (GSA) cross section of 7x10-18 cm2 near 1.3 m and negligible excited state absorption (ESA) permits Q-switching of 1.3 and 1.44 m Nd-lasers without intracavity focusing both with flash-lamp and diode-laser pumping. Negligible excited-state absorption results in high contrast of Q-switch, i.e. the ratio of initial (small signal) to saturated absorption is higher than 10. Finally, excellent optical, mechanical, and thermal properties of the host crystal give an opportunity to design compact and reliable laser sources with this passive Q-switch.
