Single longitudinal mode, 3 MHz frequency stable, 11mJ, type II doubly resonant OPO/OPA for CO_2 DIAL

摘要

For CO_2 differential-absorption LIDAR, the single-mode output of a type-II PPLN entangled-cavity nanosecond doubly-resonant OPO emitting at 2.05 μm is amplified to 11 mJ, with 3 MHz rms frequency stability and a M~2 < 1.9.
