MRL-FN-639639 nm red CW laser
639 nmThe MRL-FN-639 is a 639 nm continuous-wave 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. The TTL and analog modulation options control different things: TTL gates the beam on and off, while analog control varies its intensity. Modulation bandwidth sets how quickly the source can follow a changing command.
