Abstract

The paper discusses the application of Tm³⁺ and Tm³⁺/Ho³⁺-co-doped tellurium oxide fibres for LIDAR applications. Suitably co-doped tellurium oxide glass offers an excellent opportunity for developing high-power tunable laser compact devices, using both the 800 nm, 980 nm, and 1480 nm pumping schemes. Rare-earth ions have large solubility in tellurite glass, which we aim to exploit for designing Tm³⁺ and Tm³⁺/Ho³⁺ lasers operating in the 1.8μm and 2.9μm ranges. The importance of this wavelength band in characterising atmospheric CO₂ and OH measurements will be explained, using the following transitions in Tm³⁺:³F₄ - ³H₆ (1.8 μm), ³H₄ - ³H₅ (2.3 μm) and in Ho³⁺: ⁵I₇ - ⁵I₈ (2.1 μm) and ⁵I₆ - ⁵I₇ (2.9 μm), all of which can be achieved via the pumping schemes at above wavelengths. The paper discusses the spectroscopic characterisations of bulk glass and their applications in the design of single-mode fibres for laser experiments. For 980 nm pumping scheme, the efficient energy transfer via Yb³⁺-ion co-doping to the respective lasing levels in Tm³⁺ and Ho³⁺ is explained. The results from the steady state fluorescence spectroscopy measurements for the energy transfer analysis are explained for laser design. The paper also explains the fibre pumping scheme and laser experiments in the 1.8 μm and 2.05 μm region.
