Abstract

Abstract: The tetraphosphate glass with various Nd³⁺ dopant was prepared. The absorption and fluorescence emission spectra were measured, and the emission cross section for ⁴F_3/2 →⁴ I_11/2 transition of Nd³⁺ was calculated. Spectroscopic properties, concentration quenching, and the effect of -OH groups on the emission at 1.054μm in these kinds of the glass were investigated with diode laser at 800nm. The optimization of Nd³⁺ ion concentrations was 4.1×l0²⁰ ions/cm³. A room-temperature LiNd_0.1La_0.9P₄O₁₂ microchip laser operating at 1.054μm pumped by an AlGaAs diode laser operating at 800nm was realized.

Key words: Nd³⁺-doped, tetraphosphste glass, spectroscopic properties, microchip laser
