High-repetition-rate femtosecond optical parametric oscillator–amplifier system near 3 μm

Gary R. Holtom, Robert A. Crowell, Xi Xie

Abstract

An ultrafast laser system for the chemically important 3-μm spectral region has been constructed by means of noncritically phased-matched KTiOPO4 optical parametric gain elements. An optical parametric oscillator, synchronously pumped by a mode-locked Ti:sapphire oscillator, generates high-quality seed pulses for an optical parametric amplifier. The optical parametric amplifier, pumped by a high-repetition-rate Ti:sapphire regenerative amplifier, amplifies the seed pulses by a factor of 520. Pulses with an energy of 550 nJ and a pulse width of 160 fs are produced at a 250-kHz repetition rate in the 3-μm region.
