Abstract :
We present results of numerical and experimental investigation of beam distortions induced in the single-pass Nd:YAG crystal fiber amplifier injected by ns and ps laser pulses counter-propagating to continuous pump beam of up to 110 W power at 808 nm emitted from the fiber coupled laser diode with spectral narrowing by Bragg grating.
