The Judd-Ofelt theory is becoming basis that induced of ligand field of electric dipole transitions of between 4f electic states. It is developed for the rare earth ions through judd and of ofelt. This theory be applicate success to the raer earth ions in solid, liquid and gas state. This paper reports a optical characteristices of Nd:glass by using the Judd-Ofelt Method.
