631nm Single Longitudinal Mode Laser

【Overview】

The 631nm single longitudinal mode / single-frequency laser is a DPSS (or fibre) design delivering true single-longitudinal-mode output with narrow linewidth, long coherence length, TEM00 mode, low amplitude noise and high stability.

【Key Features】

(1) Single-frequency output, narrow linewidth, no mode hopping;

(2) Models & power: FL-631-SLM (1~1500mW);

(3) CW output, linear polarisation;

(4) Options: frequency stabilisation, AOM modulation (up to 1MHz), fibre coupling;

(5) Compact and reliable.

【Typical Applications】

Holography, Raman spectroscopy, precision measurement, biomedicine/fluorescence, atomic excitation/absorption, Brillouin scattering, quantum communication, interferometric lithography.
