摘要:
A Ti:sapphire femtosecond laser is focused into a helium filled slab waveguide to generate high order harmonics. Our results indicate that this new geometry can restrains the effect of laser defocusing and phase matching of 63rd harmonic is obtained. Asia Communications and Photonics Conferene (ACP) © OSA 2016
