Generation of tunable femtosecond pulses to as low as 172.7 nm by sum-frequency mixing in lithium triborate.
A tunable 1-kHz repetition-rate regenerative Ti:sapphire amplifier system is used to produce 200-fs vacuum-ultraviolet pulses in the range of 172.7-187 nm by phase-matched sum-frequency mixing in lithium triborate of the Ti:sapphire's fourth harmonic and a parametrically generated infrared pulse.
