Abstract

We report the generation of 14-fs pulses at $1.3 \mu \mathrm{m}$ with 80-mW average power at 100-MHz repetition rate by an all-solid-state Kerr-lens mode-locked Cr:forsterite laser. The laser spectrum covers wavelengths of 1230–1580 nm, with a FWHM of 250 nm. Since $1.3‐\mu \mathrm{m}$ wavelengths are close to the zero dispersion wavelength of Cr:forsterite, higher-order dispersion is the main factor limiting pulse durations. We use specially designed and fabricated double-chirped mirrors in combination with high-index PBH71 prisms to compensate for the intracavity dispersion over almost 300 nm.
