We demonstrate an Yb:KGW femtosecond solitary mode-locked laser oscillator, which is used as a pump source for tapered fibers to generate white-light laser pulses with an average output power of up to 2.5 W and a spectral bandwidth of over 1000 nm. By spectrally filtering these pulses and subsequent compression of the filtered pulses with a prism sequence, we are able to generate ultrashort laser pulses with durations between 26 and 65 fs that are tunable from 600 to 1450 nm and with tens to several hundreds of milliwatts of average power.
