Abstract :
Third-harmonic conversion of a CO2 laser in gaseous CD 4 with an efficiency enhanced by two orders of magnitude over that previously achieved is reported, and results which demonstrate the effectiveness of confining the nonlinear process in a hollow, dielectric waveguide are given. Power conversion efficiencies of 4.9×10-4 and 6.8×10-3 are attained in focused beam and waveguide experiments, respectively
