摘要

A mode-locked chromium forsterite laser with output power in excess of 0.7 W, a central wavelength of 1.25 μm, a pulse repetition rate of 29 MHz, and an output pulse-width-tunable from 40 to 200 fs is demonstrated. The dynamics behind the buildup of ultrashort light pulses in this laser is shown to involve spectral and temporal breathing due to the interplay of gain, Kerr nonlinearity, and dispersion effects. The pulse-width-tunable 1.25 μm output delivered by the developed laser source suggests a powerful tool for nonlinear-optical bio-imaging and offers an advantageous front end for extreme-power laser technologies.
