My research interests include laser device development, nonlinear frequency conversion and applications of optics and lasers. Laser systems developed include high beam quality pulsed metal vapour lasers (including frequency doubled systems), tunable cerium solid-state lasers, Ti:sapphire lasers, liquid and solid-dye lasers; applications include materials processing, laser micromachining, laser based high speed imaging and biophotonics. Recent work focuses on developing all-solid state cerium UV lasers including nanosecond, ultrafast and continuous wave systems, and their applications to biophotonics sensing; and plasmonics.
