“…High power mid-infrared fibre laser sources with emitting wavelengths covering the range stretching from 4 to 5.5 μm offer many applications in remote sensing, medicine and defence (Seddon 2011(Seddon , 2013Pollnau and Jackson 2008;Jackson 2012). However, in order to access these wavelengths, low phonon energy host materials are needed.…”

Numerical modelling of a Pr 3+ -doped chalcogenide glass fibre laser is presented in this paper. The spectroscopic parameters are extracted from in-house prepared Pr 3+ doped selenide-chalcogenide glass samples and used in the modelling. In this contribution, particular attention is paid to a novel resonant pumping scheme. The modelled laser performance is tested as a function of pump wavelength, fibre length, signal wavelength, fibre background loss and output coupler reflectivity. The modelling results show that the proposed resonant pumping scheme, which might be achieved in practice using a high power QCL pump, allows for a significant reduction in the laser threshold and an increase in the laser efficiency. A slope efficiency of 54% is calculated when the fibre losses are brought down to 1 dB/m.

“…We then show that this is due to a previously undocumented energy-transfer process 4 F 9/2 + 4 I 11/2 → 4 S 3/2 + 4 I 13/2 . Energy arguments suggest that this process is exothermic and very likely to occur since the energy difference between the line centers of the initial and final states is less than the maximum phonon energy of ZBLAN glass (550cm −1 ) [9]. We then measure the magnitude of this effect using two different erbium doping concentrations, and include the results in a new, more complete model of the laser.…”

Abstract:We report a new energy-transfer process in erbium doped ZBLAN glass, which is critical for optimizing the operation of lasers that use the 3.5 µm band 4 F 9/2 to 4 I 9/2 transition. The magnitude of this energytransfer process is measured for two different doping levels in Er 3+ :ZBLAN and the requirement for low doping in these lasers established.

“…Furthermore, ZBLAN fibers can have 10-100 times lower loss than silica fibers in the mid-infrared region [1]. Also, there have been recent advancements at developing light sources at mid-infrared bands [2][3][4]. As a result, the use of ZBLAN fibers will be increasingly common for fiber-based sensing applications, especially in the mid-infrared.…”
