Flash-lamp pumped normal-mode and Q-switched Cr-Tm:YAG laser performance at room temperature

摘要

Efficient solid-state lasers that operate near 2-μm wavelength at room temperature are needed for many applications. Using a flash-lamp as the pump light, we investigated normal-mode and Q-switched Cr-Tm:YAG 2 μm laser performance at room temperature. When the repetition rate was I Hz. more than 4 J normal-mode and 0.7 J/140 ns laser pulses with single transverse mode have been obtained.
