Nd3+ : YAG laser

Abstract

This article is about the Nd³⁺ : YAG laser system.

This is one of the popular four level laser systems where the trivalent neodynium Nd³⁺ ion is doped in Ytrium-Aluminium-Garnet(Y₃Al₅O₁₂), an optically isotropic crystal, commonly known as YAG. The active centres are the Nd³⁺ ions and except housing the Nd³⁺ ions The crystal atoms have no for the role in the lasing action.
