Abstract

Lanthanum Beryllate (BeL) as a laser host has been reported for the neodymium ion for the first time by Morris et al. [1] and its optical, spectroscopic and laser properties have been described in detail [2]. Ease of crystal growth, good mechanical and optical properties of BeL and sharp absorption bands of Tm³⁺ ions at diode wavelengths of 680 nm and 785 nm suggests that BeL may be a desirable alternative host for thulium. Here we present results of growth, optical characterisation and their analysis for Tm³⁺ doped BeL.
