30-fs 1.6 mJ Pulses at a kHz repetition rate from a single stage DPSS Yb amplifier

200-fs 2.5-mJ pulses from a cw-diode-pumped Yb:CaF2 MOPA are spectrally broadened in Ar and recompressed to 30 fs at 980 nm using a prism pair. Multi-millijoule 12-fs pulses are feasible upon higher-order spectral phase correction. © 2010 Optical Society of America

20-fs 1.6-mJ pulses from a cw-diode-pumped single-stage 1-kHz Yb amplifier

200-fs 2.5-mJ pulses from a fiber-oscillator-seeded DPSS Yb:CaF2 MOPA are spectrally broadened in Ar and recompressed to 20 fs using a pair of LAK14 prisms. Multi-millijoule 12-fs pulses are feasible upon higher-order spectral phase correction. © 2010 Optical Society of America

Saturable bragg reflector-based continuous-wave mode locking of yb : kgd(wo4)(2) laser

We demonstrate the saturable Bragg reflector (SBR)-based stable self-starting continuous-wave mode locking of a Yb:KGd(WO4)2 laser. With a double quantum well SBR structure the shortest pulses observed had durations of 169 fs, average powers of 18mW and an oscillating wavelength centred on 1028 nm
