MLL-F-671671 nm red CW laser
671 nmThe MLL-F-671 is a 671 nm continuous-wave solid-state laser. Light is amplified in a solid gain medium inside an optical resonator. The resonator feeds light back through that medium to build the laser beam. The pump arrangement and cooling determine how energy is supplied and waste heat is removed. Continuous-wave operation provides a sustained beam for experiments that need steady illumination.
