Professor David Shepherd

Visitor

Dave Shepherd obtained his PhD degree in laser physics from the Physics Department, University of Southampton, in 1989.

He is currently a Professor at the ORC, which he joined in 1991. He leads the Optical Parametric Oscillators group and has interests in ultrashort pulse generation, shaping and characterisation for various applications.

He also collaborates on work on high-power slab and waveguide lasers. He is a Fellow of the Optical Society of America (OSA) and a past topical editor of the OSA journal Applied Optics.
