Nd:Cr:GSGG (gadolinium scandium gallium garnet), will it replace Nd:YAG (yttrium aluminum garnet)

OSTI ID:6410785
Gadolinium scandium gallium garnet (GSGG) codoped with neodymium (Nd) and chromium (Cr) is a new laser material that can make more efficient lasers. It is compared to Nd-doped yttrium aluminum garnet (YAG) for two types of systems: large zig-zag slab lasers and small rod lasers. Nd:Cr:GSGG has a significant advantage over Nd:YAG in large systems because of its high efficiency and availability in large sizes. In small rod systems, though, the larger thermal lensing and birefringence in Nd:Cr:GSGG make it less desirable than Nd:YAG from an optical standpoint, but its high efficiency means that laser system size and weight can be reduced. Progress in obtaining large Nd:Cr:GSGG slabs is reviewed. In this effort, Allied-Signal Corp. has successfully grown 5-inch diameter Nd:Cr:GSGG boules. 22 refs.
