Abstract

Without cavity dumping or external amplification, we report a femtosecond Cr:forsterite laser with a 1.4 W output power and 2 W in continuous wave (CW) operated with a crystal temperature of 267 K. In the femtosecond regime, the oscillator generates Kerr-lens-mode-locked 84 fs pulses with a repetition rate of 85 MHz, corresponding to a high 16.5 nJ pulse energy directly from a single Cr:forsterite resonator. This intense femtosecond Cr:forsterite laser is ideal to pump varieties of high power fiber light sources and could be thus ideal for many biological and spectroscopy applications.
