AO-S-349-FL349 nm UV Q-switched pulsed laser
349 nmThe AO-S-349-FL is a 349 nm nanosecond 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. Pulse duration sets how briefly the energy is delivered, while repetition rate sets the interval between pulses; average power alone does not describe the peak intensity at the sample. Pulses lasting approximately 5 ns deliver the energy in a brief interval; pulse energy and focused spot size determine the intensity at the sample.
