Abstract :
Summary form only given. Mode-locked operation at 15 MHz has been demonstrated using a novel and long-cavity laser with a multi-pass long cavity (MPC). We successfully obtained 0.5 MW peak power and 20 fs nearly transform-limited pulse from Kerr lens mode locked (KLM) Ti:Al/sub 2/O/sub 3/ laser. This unprecedented low repetition rate laser suggests new approaches for achieving MW-level peak powers from laser cavities.
