Adaptive pulse shape control in a diode-seeded nanosecond fiber MOPA system

By K.T. Vu, A. Malinowski, D.J. Richardson, F. Ghiringhelli, L.M.B. Hickey and M.N. Zervas


We demonstrate active shaping of the driving electrical pulses to a laser diode in order to compensate for the pulse shaping effects of gain saturation in an Yb doped fiber amplifier cascade and to allow the generation of user defined customized output pulse shapes. In particular we demonstrate the generation of square output pulses, which have the potential to significantly increase the maximum pulse energy extractable from an amplifier before the peak power reaches the threshold for SRS, and for high efficiency frequency conversion
