Abstract

We report on a tunable regenerative amplifier that is operational in the near-infrared spectral region from 1230 to 1280 nm based on the vibronic laser material Cr:forsterite. Utilizing the technique of chirped-pulse amplification, we generated pulses as short as 150 fs at 1255 nm at a repetition rate of 1 kHz. Pulse amplification of more than 5 × 105 times was observed, with recorded output pulse energies of 34 μJ . Implementation of a second-harmonic generator yielded 110-fs-duration pulses of 7-μJ energy at 625 nm.
