Ultrafast rainbow: efficient solid-state source of ultrashort pulses from mid-IR to UV

By using Type II phase matching, a significant improvement of the OPA system has been achieved. Up to 60% quantum conversion efficiency is achieved in the whole range of tunability. Microjoule energies in 100-fs pulses are achieved in the mid-IR range, opening a new field of strong-field interactions in the spectral range of the vibrational frequencies of the molecules. By using various frequency-mixing schemes, tunable pulses can be achieved from 12 m to 250 nm at kHz repetition rate.
