Laser cutting techniques use lasers to slice material. This technique is very fond of hobbyists and is also widely used in industrial use. In this blog we will learn what is Laser cutting and its different types.
Laser Cutting: The rapid growth of technology and computers led to many new inventions in the manufacturing sector.
One of those remarkable achievements is the CNC Machining process.
It has helped industries to develop high-precision metal parts for engineering development.
In this article, we will discuss the basics of Laser Cutting which is again one of the types of CNC machining.
The laser cutting process is used not only for cutting metal sheets but also for other materials like clothes, rubber, etc.
There are many benefits of using the LASER beam for cutting metal. We will discuss them later in this article.
Overall, it is a very popular manufacturing process; understanding it will help you a lot.

Laser stands for Light Amplification Using Stimulated Emission of Radiation.
Using this LASER technology, we can produce a narrow beam of light that can be used for various purposes.
Do not think of LASER as a usual light source because generic light sources produce light with many different wavelengths.
Let me explain,
Light is a wave.
Each wave has a wavelength. Also, different colours have different wavelengths.
Generic Light Sources
Light from generic (bulb & flashlight) sources consists of different colours.
That means such a light source consists of different waves.
Due to these different waves, the light from a bulb or flashlight seems to spread and scattered in different directions.
LASER as A light source
Unlike generic sources, a LASER comprises a single colour, i.e., Red, Blue, Green.
Such light of single colour consists of only one wave [so does the wavelength].
LASER beam is made intense and narrow by packing several waves of a single colour travelling in one particular direction.
Now, in the following section, we will learn how this intense source of light [LASER] is used for cutting the materials,
How Does LASER Cutting Work?
Laser cutting is nothing but the focusing of the kilo-watts of electrical energy onto a single spot.
This high-energy can heat, melt and partially vaporize the material it strikes.
In laser cutting, CNS is used to direct a high-power LASER beam to cut the metals (other materials).
Let’s start with the basics,
Generally, a resonator is used to create a high-power laser beam.
There are various types of laser generator,
- CO2 Laser
- Neod (Nd:YAG) Laser
- Fibre Lasers
