MPL-FN-278-L/1uJ278 nm deep-UV Q-switched pulsed laser

278 nm

The MPL-FN-278-L/1uJ is a 278 nm pulsed laser source. 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.
