摘要
Abstract
The laser crystal Tm3＋：BaY2F8 and BaY2F8 were grown by temperature gradient method.The absorption and emission spectra of Tm3＋：BaY2F8 crystal at room temperature were measured and studied.Based on Judd–Ofelt theory,the intensity parameters of Ωi（i = 2,4,6） have been fitted and values are： Ω2 = 0.364 1 × 10–20 cm2,Ω4 = 5.750 9 × 10–20 cm2,Ω6 = 2.533 9 × 10–20 cm2.The values of radiative probabilities,radiative lifetime and integrated emission cross-sections of Tm3＋-doped BaY2F8 crystal were calcu-lated.The results indicate that the eye-safe laser can be obtained because of the larger radiative lifetime and integrated emission cross-section of the 3F4→3H6 transition.The emission spectra at low temperature show that the intensity of the emission peak in-creases with decreasing temperature,while the FWHM becomes narrower.关键词
