Abstract

In this paper, we demonstrate Er³⁺ doped tellurite multi-mode microlasers in 1.5 μm-1.6 μm wavelength range fabricated via the plasma torch method. It is a simple and cost-effective method to produce microspheres with diameter ranges from 11-88 micrometers. Multimode laser output was observed with 0.98 μm pump laser. In addition, we measured luminescence and decay time of the Er³⁺ doped (0.5 mol %, 1 mol % and 2 mol %) samples.
