Abstract
A 1319 nm single frequency nanosecond pulsed laser based on injection seeded is demonstrated. The laser oscillator is injection seeded by a 1319 nm single-frequency narrow linewidth Nd:YAG nonplanar ring oscillator (NPRO), a laser pulse of repetition rate of 500 Hz, pulse energy of 2.3 mJ, pulse width of 70 ns, and jitter of <3 ns is obtained based on ramp-hold-fire resonance detection technology. Then, through a four-stage end pump laser amplifier, the pulse energy is amplified to 15.4 mJ, with a beam quality factor of M2<1.5.
