Fiber laser, has optical unit arranged within outer resonator and making resonance condition of outer resonator for one of laser emission lines, where outer resonator is arranged over deflecting mirror on coupling side of laser

摘要

The laser has an inner resonator (5), and an outer resonator (7) that surrounds the inner resonator. The inner resonator is formed of two mirrors. An optical unit is arranged within the outer resonator and outside of the inner resonator, and makes resonance condition of the outer resonator for one of laser emission lines. The outer resonator is arranged over a deflecting mirror on a coupling side of the laser.
