MSL-DU-640-W640 nm red narrow-linewidth single-frequency laser
640 nmThe MSL-DU-640-W is a 640 nm continuous-wave laser source. 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.
