Abstract
Composite Cr4+:YAG--Nd3+:YAG crystal fiber was grown by means of LHPG method. By using a high quality Nd3+:YAG as the seed and a sintered powder rod as the source rod, Cd4+:YAG can be readily grown on a Nd3+:YAG end surface. The grown crystal fiber was processed and laser action was demonstrated. Preliminary results showed that the crystal fiber is well suited to a compact passively Q-switched laser operation. A Q-switched laser output showing a 9 ns pulse duration, a 19 mW average output and a 10 kHz repetition rate was demonstrated.
