Recent advances in LMA-PCF rod Yb-fiber with pulse operation and high power laser diode
technologies have led to kilowatt-power lasers. We developed high-peak power and high-average-power
polarization-maintained Yb doped PCF rod fi ber laser system. The output power has been achieved to
186 W at a repetition rate of 250 kHz by a 40-μm PCF-LMA fi ber and a 100-μm PCF-rod type fi ber. We
obtained the maximum pulse energy 1.1 mJ at a repetition rate of 167 kHz with a corresponding peak
power of 114 kW.
