CEP-stable few-cycle pulses with more than 190 μJ of energy at 100 kHz from a noncollinear optical parametric amplifier

Furch, Federico J.; Witting, Tobias; Giree, Achut; Luan, Chao; Schell, Felix; Arisholm, Gunnar; Schulz, Claus P.; Vrakking, Marc J. J. (2017)

Noncollinear optical parametric amplifiers (NOPAs) have become the leading technique for the amplification of carrier-envelope phase (CEP)-stable, few-cycle pulses at high repetition rate and high average power. In this ...
Numerical study of spatiotemporal distortions in noncollinear optical parametric chirped-pulse amplifiers

Giree, Achut; Mero, Mark; Arisholm, Gunnar; Vrakking, Marc J. J.; Furch, Federico J. (2017)

During amplification in a noncollinear optical parametric amplifier the spatial and temporal coordinates of the amplified field are inherently coupled. These couplings or distortions can limit the peak intensity, among ...
