EO-1573-Q1573 nm infrared Q-switched pulsed laser
1573 nmThe EO-1573-Q is a 1573 nm pulsed 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 1 kHz repetition rate, successive pulses arrive about 1 ms apart.
