A simplified flash-lamp pumped high-average-power Nd:YAG nanosecond laser system based on a master oscillator power amplifier platform was developed toward outside laser remote sensing. The performance of the laser system was demonstrated, obtaining 4 J output pulse energy with a 50 Hz operating frequency. Thermal lens effects were compensated for by using only simple image relays and up to 97 % of the laser energy could be contained in the focal spot. The developed laser system was constructed using only components suitable for operation under outside conditions.
