“…Nd: ABC 3 O 7 represents a class of disordered laser gain media, 2,3 where A = Ca, Sr, Ba; B = La, Gd; and C = Ga, Al. [10][11][12][13][14] For laser crystals, thermal and optical properties are very important for application to laser operation. The reported thermal conductivity of both materials is greater than 11 W m −1 K −1 ͑Ref.…”

A disordered Nd: SrGdGa 3 O 7 ͑Nd:SGGM͒ laser crystal was grown by the Czochralski method. The space group and effective segregation coefficient of Nd 3+ were determined to be P42 1 m and 1.36, respectively. Thermal properties, including the average linear thermal expansion coefficient, thermal diffusivity, specific heat, and thermal conductivity were measured. It was found that the thermal conductivity increases with increasing temperature, indicating glasslike behavior. Sellmeier's equations were fitted by measuring the refractive indices in the range of 253-2325 nm. The polarization absorption and emission spectra were measured at room temperature, and Judd-Ofelt analysis was carried out to calculate the fluorescence branching ratios from the upper 4 F 3/2 state and the fluorescence lifetime. The stimulated emission cross section for the 4 F 3/2 → 4 I 11/2 transition was calculated to be 2.00ϫ 10 −20 cm 2 . Finally, a diode-pumped laser experiment at 1.06 m is described. Thermal, optical, and laser properties have shown that Nd:SGGM crystals are promising for use as disordered laser materials.
