We demonstrate a new and extremely compact design for a directly diode-pumped Yb:glass laser oscillator that is used as femtosecond light source for supercontinuum generation. The laser is capable of generating femtosecond pulses of 150 fs and pulse energies up to 39 nJ at a repetition rate of 20 MHz. By using a Herriott-type multi-pass cell, 70 % of the total resonator length are folded to only 30 cm. With off-the-shelf components, our setup has a footprint of 62 × 23 cm2. Using smaller mechanical components, the size can easily be further decreased. In combination with a tapered fiber, the laser forms a cheap, stable, and compact femtosecond supercontinuum source with up to 400 mW of average whitelight power.
