| Abstract: | Tunable mid-infra-red radiation by singly resonant optical parametric oscillation based on KTA crystal pumped by multi-axial
Gaussian shape beam from Q-switched Nd:YAG laser has been demonstrated. Threshold energy of oscillation at different idler
wavelengths for different cavity length has been demonstrated. Single pass conversion efficiency of incident pump energy to
infra-red wavelength has also been measured. |
