Generation of 150-fs tunable pulses in Cr:LiSrAlF_6
We report ultrashort-pulse generation in a Cr:LiSrAlF 6 solid-state laser. The 15-mm crystal was pumped by 1 W of red light from a cw krypton laser and actively mode locked at an 82-MHz repetition frequency using an acousto-optic modulator. Wavelength tuning was demonstrated over the range 800-880 nm, limited by the bandwidth of the optical components. By including intracavity dispersion compensation, pulse widths of 150 fs were obtained with evidence that self-phase modulation contributes to spectral broadening and pulse shortening.doi:10.1364/ol.17.000195 pmid:19784273 fatcat:4lfthfxyofbelauhupi5m2ad5e
