Abstract

The invention discloses erbium neodymium ion co-doped tellurium fluoride glass for emitting 2.7 microns of intermediate infrared light. The glass comprises the following components in the range of mole percent: 55-65% of TeO2, 10-20% of GeO2, 0-20% of ZnO, 0-5% of Na2O, 0-20% of ZnF2, and 0-5% of NaF, and 0.5-1% of RE2O3, (RE is rare earth elements Er and Nd). The glass is prepared by a melting method of a corundum crucible and a silicon carbide rod electric furnace. The glass is transparent, not easy to devitrify, high in near infrared transmittance near 2708nm, and excellent in physical and chemical properties; the stability parameter delta T is greater than or equal to 140 DEG C; a strong 2.7 microns of intermediate infrared fluorescence can be obtained under pumping of a laser diode with 808nm of wavelength; and the glass is suitable for preparation and application of special glass doped with erbium ion for emitting 2.7 microns of intermediate infrared light and an optical fiber material.

Description

technical field [0001] The invention relates to a erbium neodymium ion co-doped tellurium fluoride glass emitting light at 2.7 μm in mid-infrared. Background technique [0002] Erbium ion-doped 2.7μm output solid-state lasers have attracted increasing attention in recent years because their wavelengths are very close to the absorption peak of water. field has important applications. Erbium ions are passed through 4 I 11 / 2 → 4 I 13 / 2 The transition achieves fluorescence emission near 2.7 μm, but due to the lower energy level 4 I 13 / 2 upper level 4 I 11 / 2 The long life, so can not get effective near 3μm wavelength fluorescence emission, usually by introducing other rare earth ions to reduce Er 3+ The lower energy level lifetime of the ions, resulting in an effective 2.7 μm fluorescence emission. Neodymium ions are rich in energy levels and compatible with erbium ions 4 I 13 / 2 The energy level is close to the abundant energy level, which is conducive to the lower en...
