A medium infrared solid-state laser, based on ZBLAN fibre doped with trivalent dysprosium ions, emitting at the wavelength λ = 3 μm is designed. Single mode laser emission is obtained through in-band pumping at λ = 2.8 μm. In order to accurately investigate the feasibility and the performance of the device, the rate equation approach is exploited and realistic parameters for the fibre and the rare earth are considered. A maximum slope efficiency of about n s = 54% and a threshold power P th in the 150-250 mW range are predicted.

Abstract
A medium infrared solid-state laser, based on ZBLAN fibre doped with trivalent dysprosium ions, emitting at the wavelength λ = 3 μm is designed. Single mode laser emission is obtained through in-band pumping at λ = 2.8 μm. In order to accurately investigate the feasibility and the performance of the device, the rate equation approach is exploited and realistic parameters for the fibre and the rare earth are considered. A maximum slope efficiency of about n s = 54% and a threshold power P th in the 150-250 mW range are predicted.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
