ER-TM-HO-DOPED LASER GLASS EMITTING LIGHT AT 2MUM WAVELENGTH

摘要

PURPOSE: To provide laser glass, capable of providing a homogeneous material having larger dimensions than those of a laser crystal and high luminous intensity at 2μm wavelength. ;CONSTITUTION: This fluoride laser glass comprises 2-10mol% Er³⁺, 2-11mol% Tm³⁺ and 0.5-5mol% Ho³⁺. The laser glass contains, e.g. Zr, Hf, Al, Mg, Ca, Sr or Ba as cations other than the Yb, Tm and Ho and at least fluorine as an anion. A laser beam at 2μm can be emitted by irradiating this laser glass with a semiconductor laser beam at 0.68μm wavelength.;COPYRIGHT: (C)1994,JPO&Japio
