A regenerative amplifier for femtosecond pulses that operates at a wavelength off the peak gain of Ti:sapphire is reported. Apair of prisms and an adjustable slit are used in the intracavity space so that the operating wavelength can be tuned to 745 nm. The amplified and compressed pulse is 92 fs (Gaussian profile assumed) at an energy of 1 mJ. The pumping efficiency is 12.5%.
