Abstract

A tunable femtosecond solid-state amplifier system that uses only 3 W of 488-nm argon-ion pump power has been demonstrated to deliver microjoule pulses at repetition rates up to 20 kHz, with a maximum pulse energy of 14 μJ obtained at 5 kHz. An all-solid-state, tunable, diode-pumped Cr:LiSrAlF₆ regenerative amplifier has been demonstrated, for the first time to our knowledge, that amplifies femtosecond pulses to energies exceeding 1 μJ at up to a 16-kHz repetition rate.
