ABSTRACT We report on a master-oscillator ytterbium-doped fiber amplifier system with up to 133 W of continuous-wave output power using a tunable narrow-linewidth external-cavity diode laser seed source. Stable tunable high-power operation was demonstrated from 1040 nm to 1085 nm with more than 12 dB suppression of amplified spontaneous emission.

    ABSTRACT: A radially polarized beam was amplified up to 1.1 W by passing through an Yb-doped double clad fiber pumped by a semiconductor laser, maintaining both the polarization and intensity patterns of the input beam.

    ABSTRACT: We present a high-power ytterbium fiber amplifier based on active tapered double-clad fiber (T-DCF) and capable of high single-pass gain. The T-DCF power amplifier seeded with a 320 mW narrow-band signal generates up to 110 W of average output power corresponding to more than 25 dB gain. The amplifier exhibits near-diffraction-limited beam quality (M^2 = 1.06) at the highest output power, which was limited by the available pump power. With a broadband seed source, the amplifier produced a gain of nearly 40 dB obtained for low-signal limit of the seed. The high output power combined with high gain is achieved owing to amplified spontaneous emission (ASE) filtering and increased stimulated Brillouin scattering (SBS) threshold inherent to the axially non-uniform geometry. The amplifier operates efficiently with a wide range of input seed powers thus providing the basis for one-stage tapered amplifier which combines the functions of preamplifier and power amplifier and can be a competitive alternative to multi-stage design.

    ABSTRACT: Amplification of a radially polarized laser beam is demonstrated by use of an Yb-doped double-clad fiber whose core cutoff wavelength for the LP11 mode is larger than the wavelength of the input beam. The beam power is amplified while maintaining the intensity and polarization distributions. The amplified spontaneous emission becomes negligible with increasing input power. The measured slope efficiency is 48%, and the output power is 1.1 W.
