High-power, ultra-stable, single-frequency operation of a long, doped-fiber external-cavity, grating-semiconductor laser.
Robust high-power, single frequency operation of semiconductor external cavity lasers is demonstrated in a novel extended two-level dopedfiber absorbing system. Outstanding wavelength and line-width stability is observed in long external cavities.
