【Abstract】 Recently,in virtue of the develop of the semiconductor laser and the doped laser materials with rare earth ions,the up conversion laser with resonant pump has became a scientific subjuct in great demand.The doped oxyfluoride galss ceramic with rare earth ions is a very excellent material,its optical property and chemical stability are autstanding.So,absorption spectrum of Er 3+ in Fluoroxide glass ceramic was measured,and intensity parameters Ω λ were calculated using Judd Oflet theory.Some predicted spectroscopic parameters of the excited states,like the spontaneous radiative transition rate,branching ratio and intergrated emission cross section were given.更多还原
