FL-618-SLM618 nm orange single-frequency low-noise fiber laser
618 nmThe FL-618-SLM is a 618 nm continuous-wave fiber laser. A seed laser establishes the optical signal, and a fiber amplifier increases its power while guiding the light in active fiber. 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.
