摘要

测量了0.8 at.-% Nd3+:Y0.5Gd0.5VO4的吸收光谱和荧光发射谱,光谱显示该晶体在808.5 nm有很强的偏振光吸收峰,且π偏振光(E∥C)吸收远强于σ偏振光(E⊥C)吸收,半高宽度分别为4.5 nm和12 nm,吸收截面分别为19.69×10-20 cm2和6.41×10-20 cm2;其荧光发射( 4F3/2→ 4I11/2跃迁)峰值波长在1064 nm,半高宽度为3.7 nm; 4F3/2→ 4I11/2跃迁的荧光寿命为110 μs;光谱特性表明Nd3+:Y0.5Gd0.5VO4晶体是潜在的高效率激光晶体材料.

Abstract

In this paper, the absorption spectrum and the fluorescence (or emission) spectrum of the Nd 3+∶ Y 0.5Gd 0.5VO 4 crystal were measured; Its strong absorption wavelength is at 808 5 nm; Its π polarized absorption is stronger than its σ polarized absorption and their FWHM are 4 5 nm and 8 5 nm, respectively, their absorption cross section are 19 69×10 -20 cm 2 and 6 41×10 -20 cm 2, respectively; Fluorescence (or emission) spectrum FWHM at 1064 nm is 3 7 nm; Its fluorescence lifetime is 110 μs (Nd:0.8at.-%); These properties show that Nd3+:Y0.5Gd0.5VO4 crystal is a kind of potential efficient laser material.
