Multikilohertz Ti:A1(2)O(3) amplifier for high-power femtosecond pulses.
We amplified femtosecond pulses at repetition rates of as much as 7.2 kHz in a Ti:Al(2)O(3) regenerative amplifier pumped by a frequency-doubled Q-switched Nd:YLF laser. Energies of as much as 1 mJ at 1 kHz and 85 microJ at 7.2 kHz in a 150-fs pulse have been obtained. This source was used to produce 1 W of femtosecond white light through spectral continuum generation.
