Abstract
We report a doubly resonant continuous-wave CO2 laser frequency-quadru pling device that generates 200 nW of 2.55-mu m (4 omega) and as much as 2 mW of 5.1-mu m (2 omega) radiation out of 1.7-W fundamental radia tion at 10.2 mu m (omega). The quadrupling process results from two re sonant cascading second-harmonic generations by use of a walk-off-comp ensated twin AgGaSe2 device (omega --> 2 omega) and a ZnGeP2 nonlinear crystal (2 omega --> 4 omega).
