摘要: We report on an efficient, narrow linewidth, two-stage fiber amplifier at 1014.8 nm based Yb-doped double-clad fibers. The fibers are cooled to liquid-nitrogen temperatures in order suppress absorption the operating wavelength. achieved output powers of up 5.0 W a linewidth less than 3 MHz by seeding with radiation from external cavity diode laser.
