High-power Nd:YAG laser end pumped by a cw, 10 mm ×1 µm aperture, 10-W laser-diode bar
Abstract
A Nd:YAG laser is end pumped with a 10-W laser-diode bar to produce 1.9 W of TEM(00)-mode power at 1.064 micron. The 10 mm x 1 micron bar is imaged into a 1.8 mm x 390 micron elliptical laser mode. Q-switched operation results in pulse energies of 160 micro-J at a 10-kHz repetition rate, which rises to 250 micro-J at 5 kHz. Frequency doubling in KTP produces 75 micro-J pulses at 10 kHz, corresponding to 750 mW of average power at 532 nm and a nonlinear conversion efficiency of 47 percent.
