Abstract

A Nd:YAG laser is end pumped with a 10-W laser-diode bar to produce 1.9 W of TEM₀₀-mode power at 1.064 μm. The 10 mm × 1 μm bar is imaged into a 1.8 mm × 390 μm elliptical laser mode. Q-switched operation results in pulse energies of 160 μJ at a 10-kHz repetition rate, which rises to 250 μJ at 5 kHz. Frequency doubling in KTP produces 75-μJ pulses at 10 kHz, corresponding to 750 mW of average power at 532 nm and a nonlinear conversion efficiency of 47%.
