MIL-U-946-SU946 nm near-infrared CW laser
946 nmThe MIL-U-946-SU is a 946 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. Continuous-wave operation provides a sustained beam for experiments that need steady illumination.
