Paper Abstract

We present a novel high power all-fiber-based master oscillator power amplifier (MOPA) laser system operating in the C-band (1.5 mm) with pulses <5ns and a repetition rate range of 200 kHz. This system generates >4 Watts of average power and a maximum pulse energy of 20 mJ and peak power of 5 kW at 200 kHz using custom designed Er:Yb co-doped double-clad fibers. This system was also operated at reduced repetition rates of 6 kHz and pulse energy of 165 mJ was generated with a peak power of 28 kW. By shortening the seed pulses a peak power of up to 33.9 kW with a pulse energy of 73 mJ was achieved at 20 kHz. A beam quality of M2=1.2 was achieved, which makes this system very suitable for scanning lidar applications.
