29402940 nm infrared pulsed laser
2940 nmThe 2940 is a 2940 nm pulsed 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 0.9 ms deliver the energy in a brief interval; pulse energy and focused spot size determine the intensity at the sample.
