OEM-AO-21202120 nm infrared Q-switched pulsed laser
2120 nmThe OEM-AO-2120 is a 2120 nm nanosecond diode-pumped solid-state laser. 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 10 kHz repetition rate, pulses lasting approximately 60 ns arrive about 100 µs apart.
