We demonstrate a directly diode-pumped high energy Yb:KYW laser oscillator delivering pulse energies up to 1 µJ and pulse durations down to 430 fs, thus pulse peak powers exceeding the MW level. The pulse repetition rate is 9 MHz and the average power is on the 10-W-level. The laser setup is compact and fits in a 60 × 40 cm footprint. Fiber-based pulse compression led to 60-fs pulses of 0.42 µJ pulse energy which corresponds to a peak power of 7 MW.
