Abstract

We report a doubly resonant continuous-wave CO₂ laser frequency-quadrupling device that generates 200 nW of 2.55-μm (4ω) and as much as 2 mW of 5.1-ωm (2ω) radiation out of 1.7-W fundamental radiation at 10.2 μm (ω). The quadrupling process results from two resonant cascading second-harmonic generations by use of a walk-off-compensated twin AgGaSe₂ device (ω → 2ω) and a ZnGeP₂ nonlinear crystal (2ω → 4ω).
