EO-355-PS355 nm UV mode-locked pulsed laser
355 nmThe EO-355-PS is a 355 nm picosecond diode-pumped solid-state laser. The specified pulse energy is 1–40 μJ at 200 kHz. 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. Mode locking fixes the phase relationship between resonator modes so they add together into a regular train of short pulses. Pulse duration and pulse spacing describe different time scales. Pulses shorter than 15 ps deliver the energy in a brief interval; pulse energy and focused spot size determine the intensity at the sample.
