AO-K-289/1-5uJ289 nm deep-UV Q-switched pulsed laser

289 nm

The AO-K-289/1-5uJ is a 289 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.
