“…[1] and will not be repeated here, although they broadly fall under two categories: passive and active phase-compensation techniques. Specific implementations include evanescent-wave coupling [6][7][8][9][10][11][12][13][14][15][16], common-cavity coupling , compensation of phase errors using phase-conjugate elements [39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54], and phase detection with active compensation techniques [55][56][57][58][59][60][61][62][63][64][65][66][67], These demonstrations range from subwatt levels [9,17,56,60,62], to 10 W levels [10,20,55,…”

Fiber lasers are well suited to scaling to high average power using beam-combining techniques. For coherent combining, optical phase-noise characterization of a ytterbium fiber amplifier is required to perform a critical evaluation of various approaches to coherent combining. For wavelength beam combining, we demonstrate good beam quality from the combination of three fiber amplifiers, and we discuss system scaling and design trades between laser linewidth, beam width, grating dispersion, and beam quality.

“…In addition to the direct application of PCMs as laser mirrors also double-pass amplifiers have been investigated using a PCM between the first and second pass through the amplifier rod [7][8][9][10][11][12][13][14][15][16]. The light is coupled out with a polarizer and a quarter wave plate which rotates the polarization of the linearly polarized light by 900 after two passes.…”

Using phaseconjugating mirrors (PCMs) the beam quality of solid state lasers can be improved by compensating the thermal lens of the rods at high average powers. Oscillators with one PCM as highly reflecting mirror and double-pass amplifiers with PCMs have been investigated. PCMs are realized by stimulated Brillouin scattering (SBS). Nd:YAG and Nd,Cr:GSGG oscillators have been built with pulse repetition rates up to 45 Hz. Stable TEM00-mode operation has been obtained. Average output powers of 10 Watts for 15 ns Q-switched pulses ofa Nd:YAG-laser and 7 Watts for Nd,Cr:GSGG have been achieved. In a double pass Nd:YAG-amplifier the thermal lens was compensated leading to a nearly diffraction limited beam with a maximum output power of 40 Watt.
