Direct diode-pumped Kerr-lens mode-locked Ti:sapphire laser

Opt Express. 2012 Jun 18;20(13):13677-83. doi: 10.1364/OE.20.013677.

Abstract

We describe a Ti:sapphire laser pumped directly with a pair of 1.2 W 445 nm laser diodes. With over 30 mW average power at 800 nm and a measured pulsewidth of 15 fs, Kerr-lens-modelocked pulses are available with dramatically decreased pump cost. We propose a simple model to explain the observed highly stable Kerr-lens modelocking in spite of the fact that both the mode-locked and continuous-wave modes are smaller than the pump mode in the crystal.
