Abstract :
The paper illustrates the design and the optimization of a medium infrared (Mid-IR) microstructured fiber laser based on dysprosium doped chalcogenide glass, Dy3+:Ga5Ge20Sb10S65. The investigation is performed realistically, by taking into account the spectroscopic parameters measured on samples of the aforesaid glasses. The aim is to investigate the feasibility of optical beam generation close to 4.4 μm wavelength. An output power of 107.2 mW with an input pump power of 1 W is calculated. This result indicates that the designed laser configuration can lead to a feasible medium infrared source which could find application in optical free propagation, biomedicine and sensing.
