Abstract

A 100-GW optical parametric chirped-pulse amplifier system is used to study nonlinear effects in the 1.54 µm regime. When focusing this beam in air, strong third-harmonic generation (THG) is observed, and both the spectra and efficiency are measured. Broadening is observed on only the blue side of the third-harmonic signal and an energy conversion efficiency of 0.2% is achieved. When propagated through a 10-cm block of fused silica, a collimated beam is seen to collapse and form multiple filaments. The measured spectral features span 400–2100 nm. The spectrum is dominated by previously unobserved Stokes emissions and broad emissions in the visible.
