Abstract

Ultrafast supercontinua are marvellous when generated in χ3 bulk, where they retain the coherence properties of their seed pulses. Such true “white laser light” is alluring to biology, chemistry and physics. However, effects such as self-focussing and filamentation fundamentally constrain its pulse energy to less than few micro-joules. Having stronger supercontinua can enhance our limit of detection in spectroscopy and accelerate micromachining. Thus, we present a novel method for supercontinuum generation in theory and experiment, liberating the fundamental energy constraints. Our preliminary world-first results indicate a doubled conversion efficiency and 104 stronger, few femtosecond pulses, compared to conventional methods.
