Modeling of a mid-IR chalcogenide fiber Raman laser.
A computer model using a finite element technique was written to model the behavior of a chalcogenide fiber Raman laser. The model demonstrates the feasibility of a middle infrared fiber Raman laser pumped at 5.59-microm by a carbon monoxide laser and operating at a wavelength of 6.46-microm. This wavelength may be of interest in surgical applications since it corresponds to the amide II absorption. Calculations show slope efficiencies can approach 80% with moderate threshold powers.
