Keywords:fiber laser, harmonic generation

In the experiment of frequency conversion of coherently combined four beams, the output power of 295 W (corresponding efficiency of >63%) and 82 W (>40%) were obtained for the second and third harmonics, respectively, as a result of improved thermal management of nonlinear crystal.
