Laser Cutting 101 – How it Works

LASER stands for Light Amplification by Stimulated Emission of Radiation. A laser cutter is a machine that cuts thick materials with great precision and at high speeds directed by a CNC (Computer Numerically Controlled) machine. Different types of lasers are used to cut a variety of materials the principle remains the same: energy is converted into a highly focused, high density beam of laser light. Everything in its path is burned, vaporised or melted. This process has various benefits, including:

  •      Extreme precision, allowing inexpensive manufacturing of even very small objects.
  •      High quality cut surfaces that seldom requires additional finishing.
  •      Commercially manufacturing objects that would be extremely expensive to manufacture by any other method.

Futuristic Laser Cutting – Setting the Industry Standard

After humble beginnings, the original laser was made based on stimulating a ruby crystal and was of low power. Modern industrial laser cutting machines are mostly fiber laser cutting, CO2 or neodymium lasers. Fiber laser cutting uses a beam that is created using a ‘seed laser’ which is then amplified using glass fibers and pump diodes. A fiber beam is around 100 times more intense than that of a CO2 laser and it can work with all kinds of metals – perfect for most projects across a wide range of materials, requiring precision and accuracy.
