Abstract

We present a Kerr-lens-modelocked Ti:sapphire laser pumped by a single green laser diode and producing 48-fs pulses at a repetition rate of 1 GHz. The laser average output power was 150 mW, corresponding to a peak power of 3 kW, which is shown to be sufficient to permit supercontinuum generation without further optical amplification. Self-starting behavior was routinely observed, enabling turn-key operation. The entire laser system occupied a footprint of 400 mm × 275 mm, allowing it to be compatible with a standard 19-inch rack unit.
