EO-1064-N1064 nm near-infrared Q-switched pulsed laser
1064 nmThe EO-1064-N is a 1064 nm nanosecond diode-pumped solid-state laser. The specified pulse energy is 0.3–1.5 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.
