19081908 nm infrared narrow-linewidth fiber laser
1908 nmThe 1908 is a 1908 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. At the nominal 80 MHz repetition rate, successive pulses arrive about 12.5 ns apart.
