MDL-PS-445445 nm violet pulsed laser
445 nmThe MDL-PS-445 is a 445 nm picosecond direct diode laser. Electrical current creates optical gain in a semiconductor junction, and the diode generates the laser light directly. Optical feedback selects the oscillating modes, while drive current and junction temperature affect output power and wavelength. 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.
