Raman enhanced supercontinuum generation from 2-20 μm in GaAs using 3 ps CO_2 laser pulses

摘要

Supercontinua covering the entire mid-IR region were obtained by sending a train of 3 ps CO_2 laser pulses through a 67mm GaAs crystal. The spectral width is attributed to stimulated Raman scattering and self-phase modulation.
