Abstract

The stimulated emission cross section of Nd:YAG (yttrium aluminum garnet) (4F3/2→4I11/2) was compared to the known cross section of Nd:ED-2 glass at 1060 nm. Small samples of Nd:YAG and ED-2 glass were end pumped with a chopped cw 514.5-nm argon-ion laser in an identical geometrical arrangement. The stimulated emission cross section obtained for Nd:YAG at 1064 nm was found to be 7.6 ×10−19 cm.
