UV-FN-349-X349 nm UV narrow-linewidth single-frequency laser
349 nmThe UV-FN-349-X is a 349 nm continuous-wave diode-pumped solid-state laser. Laser diodes optically pump a solid gain medium inside a resonator. The pump supplies the energy; repeated passes through the gain medium amplify the laser light. Continuous-wave operation provides a sustained beam for experiments that need steady illumination.
