| Abstract: | Raman lasers consisting of microsphere coupled to a tapered fiber greatly reduce threshold and enhance efficiency. This paper investigates performance of the Raman laser theoretically in detail. Firstly it deals with deducing the equation for pump threshold in microspherical Raman lasers based on rate equations in considering simultaneously pump and Raman signals. Then, we investigate characteristics of coupling between microsphere and tapered fiber, and the threshold dependence on coupling is considered. Some propositions for improving the efficiency of microspherical Raman lasers are also discussed. Totally, based on theoretical simulation, we try to enhance performance of Raman lasers by improving its'system of coupling. |
