Glossary of laser cutting terms - N


Nesting/Nesting Capabilities

Part-on-part nesting capabilities optimizes material use, reducing material waste, and increasing cost-effectiveness. Stacking or nesting optimizes material and can significantly reduce cutting times.

Nd:Glass Laser

A solid-state laser of Neodymium glass offering high power or short pulses, or both, for specific industrial applications.

Nd:YAG Laser

A solid-state laser of Neodymium:Yttrium-Aluminum Garnet, similar to the Nd:glass laser. Both are pumped by flashlamp. Beam transmission is via fiber optics. Power is up to 4,000 watts. The wavelength is 1.06 micrometers. Nd:YAG laser light can perform finer detail work and is better suited for work on highly reflective materials than CO2 laser light. See CO2 Laser and Nd:Glass Laser.

Nickel Alloys

Nickel alloys include a variety of metals such as Monels, Inconels, Nimonics, Hastalloys, and Renes. These metals are cut in ways similar to stainless steels. Nitrogen is often used as a cutting gas to achieve a metallurgically pure edge.

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. See Maximum Permissible Exposure.


An element of Gas Jet used for cutting. The nozzle is used to constrict and direct the assist gas to produce a columnar flow. The flow of gas serves to push the molten metal through the kerf. Nozzles vary in shape and exit orifice. (Common orifice diameters are 0.040" and 0.060".)
