Abstract
The presence of excited state absorption at the 1.06 μm lasing wavelength of Nd doped glasses is demonstrated. The excited state absorption cross-section for silicate (LG680) and phosphate (LG760) glasses was extracted from gains measurements associated to a theoretical model which is described in this paper. From both measurements and the Judd–Ofelt formalism calculation, we show that excited state absorption effect in Nd-doped glasses is at the origin of non-unity quantum yield. The values obtained imply that excited state absorption in Nd doped glasses may constitute a significant optical loss, especially for silicate glass.
