TUN-1054~10741073 nm near-infrared tunable single-frequency laser
1073 nmThe TUN-1054~1074 is a 1073 nm continuous-wave 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. Continuous-wave operation provides a sustained beam for experiments that need steady illumination.
