ABSTRACT: We report a high-peak-power, single-polarized master
oscillator power amplification system employing polarization- maintaining
Yb-doped rod-type photonic crystal fiber. The MOPA system comprises of a
Q-switched microchip laser generating ~630ps pulses at 8.6 kHz repetition-rate
and two amplification stages employing double cladding fiber and rod-type PCF
respectively. The MOPA system obtains narrow spectral bandwidth, single-polarized
pulses of 9W maximum output average power, corresponding to peak power of
1.7MW.
