Abstract

We show that near-transform-limited 32-fs pulses can be generated directly from a self-mode-locked titanium-doped sapphire oscillator. The laser operates at a center wavelength of 813 nm with a bandwidth of 22 nm in a TEM₀₀ mode. Correct choice of the glass for the intracavity prism pair results in improved compensation of group-velocity dispersion, which yields near-transform-limited output pulses. Compensation for group-velocity dispersion in the output coupler and autocorrelator optics is necessary in order to measure this transform-limited pulse width.
