Abstract

A microjoule level diode-pumped femtosecond Yb:KYW laser oscillator is demonstrated, delivering up to 1 &mgr;J pulse energies and 430 fs pulse duration, resulting in a pulse peak powers exceeding the MW level. The pulse repetition rate is about 10 MHz and the average power is on the 10 W. The laser setup is extremely compact and fits in a 60 x 30 cm footprint. Fiber-based pulse compression of the oscillator pulse train leads to 60-fs pulses of 0.42 &mgr;J pulse energy which corresponds to a peak power of 7 MW. This laser source is ideally suited for many micro- and nano-structuring applications where high-speed and precision are required.
