MSL-R-13421342 nm infrared CW laser
1342 nmThe MSL-R-1342 is a 1342 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. Single-longitudinal-mode operation selects one resonator frequency. Linewidth describes the spread around that frequency, while frequency drift describes how its center moves over time. This distinction matters when matching the source to a narrow resonance or an interferometer.
