Stimulated emission cross section of Cr-doped GdScGa garnet

Abstract
The stimulated emission cross section is calculated on the basis of emission spectrum and spontaneous lifetime measurements. The maximum stimulated emission cross section is determined to be 0.69×1020 cm2. A comparison is made between the calculated stimulated emission cross section and one which has been determined from laser oscillation experiments. Fair agreement between them is obtained within a 20% error at wavelengths from 770 to 810 nm.
