We demonstrate an Ytterbium diode-pumped laser with >10 W average output power, pulse repetition rate up to 100 kHz, and pulse duration around one picosecond. This system does not use the chirped pulse amplification system, yet generates much shorter pulses than typical picosecond lasers. The amplified pulses are slightly chirped, and pulse duration after external compression was as short as 400 fs. The laser combines the advantages of a picosecond amplifier, i.e. no pulse stretcher and compressor, with ultra short pulse durations which makes the laser source extremely interesting for applications such as transparent or semiconductor materials processing.
