[13p-B3-4] Efficient Harmonic Generation of Pulsed High-average-power Fiber Laser (PCF) System.
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.
