Paper Abstract

Polycrystalline ceramic with activator ions has already become popular material as laser medium. In this study, composite type rod which consisted with doped- and undoped-YAG sections was prepared for the laser experiments. By the improvement of pumping chamber, pulse energy of 930 mJ was obtained from oscillator with TEM00 in normal pulse mode at 10 Hz at room temperature. Giant pulse generation was carried out by inserting an AO Q-switch into the laser cavity. Because of the limitation of surface damage thresholds on the laser rod and the mirrors, the maximum output energy up to 21 mJ was obtained.
