Diode-pumped solid-state lasers

I have experience of developing lasers and laser amplifiers based on solid-state gain media, in a variety of output formats. These include Nd-doped lasers operating around 1μm and 1.3μm, and broadly tunable Cr-doped lasers. These have been demonstrated with continuous-wave, Q-switched and modelocked outputs. Emphasis has been placed on high power and high energy operation.
