“…Lasing in a tellurite fiber was first reported in 1994 at 1.061 mi na nN d 3+ -doped fiber [4] and again in 1997 at 1.560 mi na nE r 3+ -doped fiber [5]. Both of these tellurite fiber lasers were of a single-mode design constructed using a 12%-12% cavity from Fresnel reflections from the bare fiber ends.…”

“…Stimulated Brillouin Scattering and Stimulated Raman Scattering) limiting the achievable peak power, which are exacerbated by the narrow linewidth output requirement of gas spectroscopy. Moreover due to the higher emission cross section offered by tellurite glasses with respect to silicates [4,5], there is the potential to make a more compact gain-module for the power amplifier stage in a MOPA system, like the one being developed for the ASCENDS space mission [1]. To date in our samples we have measured gains of 2 dBcm -1 at the 1535 nm peak and 0.7 dBcm -1 around 1575 nm the key wavelength of interest.…”

ABSTRACT:Tellurite glass compositions doped with erbium and erbium/ytterbium optimised to support extended gain bandwidth with significant amplification have been fabricated, and their thermal, optical absorption, excitation and luminescence properties investigated. Each rare-earth dopant concentration was set at 1x10 20 cm -3 . Broad emission cross-section bandwidths up to 50nm FWHM were observed, with fluorescence lifetimes of ~3ms. Collinear pump probe measurements on ~4mm thick bulk samples revealed peak gains of up to 2.1dB/cm at a wavelength of 1535nm in the co-doped material, with an incident pump intensity of only I inc~8 kWcm -2 at a wavelength of 974nm. At equivalent absorbed pump powers between co-doped and single doped materials the relative gain was 1.25dB/cm (I inc~4 kWcm -2 ) and 0.9dB/cm (I inc~8 kWcm -2 ) respectively, demonstrating efficient energy transfer from the ytterbium to erbium ions. Excited state absorption at longer wavelengths was observed and characterised and its implication on realising sufficient gain in the wavelength band of interest is discussed.

“…Stimulated Brillouin Scattering and Stimulated Raman Scattering) can be mitigated and enable higher peak powers despite the very narrow linewidth requirement for gas spectroscopy. Moreover due to the higher emission cross section offered by these glasses with respect to silicates [4,5], there is the potential to make a more compact gain-module for the power amplifier stage in a MOPA system. To date in our samples we have measured, with in-band pumping at approximately the saturation irradiance for the glasses, gains in excess of 2 dBcm -1 at the 1535 nm peak and 0.7 dBcm -1 around 1572 nm the key wavelength of interest.…”

ABSTRACT:New devices are required to provide effective tools for DIAL or LIDAR measurements from space, which will enable improved mapping of the concentration and distribution of CO 2 in our atmosphere. Here we present characteristics of Erdoped thin film waveguides, with an extended gain bandwidth, which are applicable to planar waveguide power amplifiers for wavelengths around the 1572 nm CO 2 absorption peaks. Planar waveguide films have been fabricated by sputtering of fluorophosphate and tellurite based glasses onto oxidised silicon wafers, and their properties characterized. The deposition parameters for undoped and Er,Yb-doped films have been assessed and studied, achieving losses of <1.5 dB/cm at 633 nm for the as deposited waveguides. A comparison between the two host materials is made and the potential performance discussed.
