Pulse transmission mode (PTM) Q-Switching of an Nd:YAG oscillator was investigated for use in airborne laser bathymetry system transmitters. Peak powers of 4.7 to 6.3 MW were generated at 1.06 μm at repetition rates up to 50 Hz with a pump energy of 6.19 joules. Frequency doubling with CD*A produced a peak power of 2.46 MW at 0.532 µm with a conversion efficiency of 52%. Pulse widths of 6 nanoseconds were obtained at 1.06 µm, and 5 nanoseconds at 0.532 µm. The pulse width was limited by the commutation time of the Q-switch driver. Operation at increased PRF is also discussed.
