DPS-355-Pico355 nm UV pulsed laser
355 nmThe DPS-355-Pico is a 355 nm picosecond 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 5 MHz repetition rate, pulses shorter than 50 ps arrive about 200 ns apart.
