Two-color fiber amplifier for short-pulse, mid-infrared generation.
A short-pulse, two-color Yb:fiber laser system has been developed for mid-infrared generation. To date, 20 microW of average power at a wavelength of approximately 18 microm is generated by difference-frequency mixing 300 mW average power from the two-color Yb:fiber amplifier. The mid-infrared power was not limited by two-photon absorption, allowing it to be scaled by increasing the amplifier power.
