1.1 kW, 100 Hz room-temperature diode-pumped nanosecond laser by water immersion cooling
Abstract
We report a room-temperature diode-pumped solid-state Nd:YAG laser by water immersion cooling, which delivers a pulse energy of 11 J at the repetition rate of 100 Hz and the pulse duration of 7 ns, while the beam quality factor is 2.6 times the diffraction limit. This represents the highest, to the best of our knowledge, performance achieved for room-temperature nanosecond lasers operating above 100 Hz, which demonstrates the great potential of room-temperature immersion-cooled nanosecond active-mirror lasers.
