AI Article Synopsis
- The study investigated how mixing the radiation from CO- and CO-lasers in different nonlinear crystals (AgGaSe, BaGaGeSe, and PbInTe) affects difference frequency generation.
- The research focused on measuring efficiency and refractive indices for converting frequencies into the long-wave infrared range of approximately 12-20 µm.
- The PbInTe crystal achieved the highest frequency conversion efficiency of 10, significantly outperforming prior results by an order of magnitude.
Article Abstract
Difference frequency generation under mixing of repetitively-pulsed CO- and CO-laser radiation in AgGaSe, BaGaGeSe and PbInTe nonlinear crystals was studied. Efficiency and refractive indices were examined for this frequency conversion into the long-wave domain of ∼12-20 µm in the mid-IR. The highest frequency conversion efficiency of 10 was obtained for a relatively new PbInTe crystal, which is an order of magnitude higher than previous results.
