Experimental observation of gain in a resonantly pumped Pr(3+)-doped chalcogenide glass mid-infrared fibre amplifier notwithstanding the signal excited-state absorption
We demonstrate a maximum gain of 4.6 dB at a signal wavelength of 5.28 μm in a 4.1 μm resonantly pumped Pr(3+)-doped selenide-based chalcogenide glass fibre amplifier of length 109 mm, as well as a new signal excited-stated absorption (ESA) at signal wavelengths around 5.5 μm. This work to the best...
