EO-532-N532 nm green Q-switched pulsed laser
532 nmThe EO-532-N is a 532 nm nanosecond diode-pumped solid-state laser. The specified pulse energy is 0.1–0.8 mJ, depending on rate and variant. 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.

Select energy and timing together
Specify pulse energy, repetition rate, pulse duration, trigger requirements and cooling for the same configuration. The maximum energy and maximum repetition rate can describe different variants. Energy per pulse is quoted in μJ, mJ or J; pulse duration is quoted in ps, ns or ms.
The 0.8 mJ configuration is specified at 3 kHz with pulse duration <11 ns. Lower-energy variants have different duration and repetition-rate limits.
