LR-1064-201064 nm near-infrared Q-switched pulsed laser
1064 nmThe LR-1064-20 is a 1064 nm nanosecond diode-pumped solid-state laser. The specified pulse energy is 50 / 80 mJ options. Select energy, timing and cooling for the same configuration. Laser diodes optically pump a solid gain medium inside a resonator. The pump supplies the energy; repeated passes through the gain medium amplify the laser light. Q-switching stores energy in the gain medium while resonator losses are high, then lowers those losses to release a pulse. Pulse energy and repetition rate must be considered together, because changing the pulse spacing changes the average power for a fixed pulse energy. At the nominal 20 Hz repetition rate, pulses shorter than 10 ns arrive about 50 ms apart.
