Development of neodymium-doped laser glass at LLNL. (Source: Wikipedia.org)

A laser whose optical medium is phosphate or silicate glass enriched, or doped, with neodymium ions. The wavelength of the neodymium-doped glass laser is 1.062 µm (for silicate glasses) and 1.054 µm (for phosphate glasses), which lies in the near-infrared band. The Nd:glass laser is very similar to the Nd:YAG laser, which uses an yttrium aluminium garnet crystal, but the glass material can be produced in larger sizes than YAG crystals. Nd:glass lasers are used, for example, in inertial confinement fusion research.
