Cavity-enhanced Optical Parametric Chirped-pulse Amplification

Abstract

The generation of few-cycle (sub-10-fs) pulses is important for optical frequency metrology, attosecond physics, and extreme nonlinear optics. There is much motivation to develop simple, robust, and inexpensive techniques for the amplification of these few-cycle pulses, especially to peak and average power levels exceeding the current limits of the Ti: sapphire laser technology. For instance, high-harmonic generation would benefit greatly from the availability of higher average power, without compromising on the peak power.
