Laser cutting system

  • LASER:

  • Light Amplification by Stimulated Emission of Radiation


  • There are two types of lasers used for cutting:

  • the gaseous CO2 laser

  • the solid-state Nd : YAG laser.


  • Wood

  • Paper

  • Leather

  • Glass

  • Ceramic

  • Metal

  • Steel, Titanium, Paper, Wax, Plastic, Fabric


  • Material limitations (including crystalline and reflective materials)

  • Producing a piercing hole that can make the pattern design more difficult.

  • Reflected laser light can present a safety hazard

Economics of laser cutters
Economics of Laser Cutters

A 1000 – watt laser beam focused to a spot .005 inch in diameter is equal to 5,000,000 watts/square inch

Beam Dia.; .005 - .009 inch

Optical unit
Optical Unit

  • Mirrors direct the beam from the source down to the lens

  • the lens then focuses the beam into the desired geometry

  • finally the assist gas is added to remove the molten metal

Laser surface engineering processes
Laser Surface-Engineering Processes

An outline of laser surface-engineering processes. Source: After N. B. Dahotre.


  • The Beam

    • .0875-.5 inches from the source

    • ~.001 inch at the work piece

  • Many factors are material and thickness dependent

    • focal length, beam intensity, reed rate, cut with (kerf), cut time, machine configuration

  • Types of cut

    • Vaporization cutting, Melt and Blow, Thermal stress cracking, Burning Stabilized

Pace makers
Pace Makers

  • Utilizes laser cutting, welding, marking.

Processes and practices
Processes and Practices

  • Current Uses of Laser Cutting Systems

    • Primarily 2D Systems

    • Either melts, burns, or vaporizes away material

    • Used to cut flat-sheet metal and piping/structural materials


  • There are many useful applications and uses for Laser Cutting in the current manufacturing market

  • Many new innovations are on their way and new uses for this versatile cutting process are cropping up each year
