Abstract

We have designed and demonstrated two wide bandwidth passive frequency doublers capable of second harmonic generation over the entire 100 nm cavity optics bandwidth of a passively modelocked Ti:Al₂O₃ laser with minimal loss in conversion efficiency. In addition, we demonstrate that focussing effects are extremely important in determining the bandwidth in sum frequency mixing of ultrashort pulses in the near VUV region. This effect is demonstrated with noncollinear sum frequency mixing performed between the fundamental and the third harmonic subpicosecond pulses of this laser source.
