Glossary of Laser Terms-N

 Nd:Glass Laser  

A solid-state laser of neodymium:glass offering high power in short pulses. A Nd-doped glass rod used as a laser medium to produce 1064 nm light.

Nd:YAG  

Laser Neodymium:Yttrium Aluminum Garnet. A synthetic crystal used as a laser medium to produce 1064 nm light.

 Neodymium (Nd)  

The rare earth element that is the active element in Nd:YAG lasers and Nd:Glass lasers.

  Nominal Hazard Zone (NHZ)  

The nominal hazard zone describes the space within which the level of the direct, reflected, or scattered radiation during normal operation exceeds the applicable MPE. Exposure levels beyond the boundary of the NHZ are below the appropriate MPE level.
