A gain switched pulsed laser based on ytterbium doped rod PCF type fiber is presented. The high performance pump system was based on 976 nm laser diodes incorporating high speed and high current laser diode drivers with active feedback loop based control that enable high pulse to pulse stability. Furthermore the temperature control ensure the adequate output spectrum of the pump laser diodes in order to match maximum of the absorption peak of Yb doped active medium. The pulses duration in range between 48 ns to 75 ns were achieved with peak powers up to 3.6 kW. Further, the change of the laser output spectrum in regard to the pump pulse power is observed.
