- This paper reports a significant improvement, >3 times, on 2-μm peak power from fully-fiberized picosecond pulse fibre lasers, enabling highly efficient onward frequency conversion of the output light into the mid-IR spectral region. The work demonstrates the high-power capability of commercially-available thulium-doped silica fibre and has attracted significant industrial attention (SPI Lasers (Dr Mike Durkin, Mike.Durkin@spilasers.com), and Cybel (Dr Robert Tench, robert.tench@cybel-llc.com) have each expressed strong interest in the work). Our laser underpins a £5.5M, 5-year collaborative, interdisciplinary project (Universities of Edinburgh, Nottingham and Southampton, SPI lasers and DSTL) on laser-based medical imaging (EPSRC Healthcare Technologies Grant - EP/T020997/1).
