Abstract

Period doubling of an 84-MHz repetition-rate Kerr-lens mode-locked Ti:sapphire laser operated at 830 nm and producing $\sim 300 \mathrm{mW}$ of average power has been observed and explained in terms of total mode locking of ${\mathrm{TEM}}_{00}$ and ${\mathrm{TEM}}_{01}$ modes in an effective confocal cavity. This configuration leads to a spatial sweeping action of a single-peaked pulse at 42 MHz. Period tripling and quadrupling is observed for certain cavity configurations.
