Cavity-enhanced sum-frequency generation of blue light with near-unity conversion efficiency
Hugo Kerdoncuff, Jesper B. Christensen, Túlio B. Brasil +4
We report on double-resonant highly efficient sum-frequency generation in the blue range. The system consists of a 10-mm-long periodically poled KTP crystal placed in a double-reso…

Compact, CO2-stabilized tuneable laser at 2.05 microns
Philip G. Westergaard, Jan W. Thomsen, Martin R. Henriksen +4
We demonstrate a compact fibre-based laser system at 2.05 microns stabilized to a CO2 transition using frequency modulation spectroscopy of a gas-filled hollow-core fibre. The lase…
