New publication on an ultrafast OPO incorporating Pellin-Broca prisms

We have a new paper published in Optics Express written by PhD student Danny Hunter. The paper, titled Ultrashort-pulsed optical parametric oscillator employing Brewster angle prism retroreflectors, uses a pair of BK7 Pellin-Broca prisms in place of cavity mirrors to produce a compact cavity that displays reduced sensitivity to misalignment.

The OPO produces chirped signal pulses which are tuneable across 1100-1350nm, and which are externally compressible to sub-150-fs durations. Power scaling is limited by crystal damage, so we will be exploring PPLT as an alternative and will also investigate CaF prisms. Well done Danny!
