Abstract :
Presents a 100-kHz femtosecond amplifier system delivering pulses with a duration of 35 fs and an energy of 7 μJ. The system does not include a stretcher, since the large amount of dispersion accumulated during the amplification process is sufficient to prevent self-focusing. Compensation in approximately all orders is achieved through a combination of a prism compressor, chirped mirrors, and a liquid-crystal modulator, allowing the amplified pulses to be shortened to nearly the bandwidth limit.
