Demonstration of high energy extraction efficiency in a laser-diode pumped high gain Nd:YAG regenerative amplifier

High energy extraction efficiency of 48±4% for the cavity mode cross section (17.5%±1% for the entire lasant cross section) and high energy gain of 71±1 dB have been demonstrated simultaneously, for the first time, in a laser-diode pumped Nd:YAG regenerative amplifier (RA). The RA was operated at an...

Zusammenfassung:High energy extraction efficiency of 48±4% for the cavity mode cross section (17.5%±1% for the entire lasant cross section) and high energy gain of 71±1 dB have been demonstrated simultaneously, for the first time, in a laser-diode pumped Nd:YAG regenerative amplifier (RA). The RA was operated at an initial small-signal gain of 3.15±0.20, an input pulse energy of 0.5±0.1 nJ (pulse width of 910±12 ps), an amplified output pulse energy of 6.0±0.3 mJ (pulse width
