PS-M-620620 nm red Q-switched pulsed laser
620 nmThe PS-M-620 is a 620 nm picosecond laser source. 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 10 ps deliver the energy in a brief interval; pulse energy and focused spot size determine the intensity at the sample.
