Laser cutting is a technology that uses a powerful laser to cut or engrave flat sheet materials such as plastic, wood, paper, fabric etc. It works by directing the output of a high-power laser, by computer, at the material to be cut. The material then either melts, burns or vaporizes away leaving an edge with a high-quality surface finish.

2. WHAT IS LASER CUTTING ?
Laser cutting is a technology that uses a powerful laser to
cut or engrave flat sheet materials such as plastic, wood,
paper, fabric etc.
It works by directing the output of a high-power laser, by
computer, at the material to be cut. The material then
either melts, burns or vaporizes away leaving an edge
with a high-quality surface finish.

3. Laser cutting is one of the most popular profiling
technologies as it has the ability to accurately cut, melt,
burn, or vaporise a range of materials such as stainless
steel, aluminium, nickel alloys, etc.
Laser Cutting Benefits
 Applicable to a wide range of materials and thickness;
 Narrow kerf widths;
 High speeds;
 High repeatability;
 Reliable;

4.  Easily automated and programmable;
 Flexibility in changeovers;
 Reduced tooling costs and reduced set-up times;
 Non-contact process (no tooling wear or breakage,
minimal material distortion);
 Versatile (the same tool can be used for laser drilling and
laser welding);
 Capacity for high degree of beam manipulation (true 3D
cutting).

5. What are the Types of Laser Cutting?
There are three main types of laser cutting.
1. Carbon Dioxide Laser
Carbon dioxide cutting lasers are
widely used in industrial settings
for both cutting and welding, and
can operate at continuous power
output of over 10 kilowatts.
Carbon dioxide lasers are known
to be very efficient, operating
with an estimated 30 percent
efficiency.

6. 2. Neodymium Laser
Neodymium lasers are often
used primarily for boring. These
lasers are typically for small or
medium sized cutting, and are
also used in a wide range of
research applications, most
notably in nuclear fusion
research.
These lasers generate pulses
as short as 10 ^ -12 seconds
long, but have peak powers of
10 ^ 9 kilowatts.

7. 3. Neodymium Yttrium-AluminumGarnet Laser
The neodymium yttrium-aluminumgarnet laser, also known as the
neodymium-YAG laser, is nearly
identical to the neodymium laser but
typically used for different purposes.
The laser can produce high-power
beams necessary for cutting. These
lasers typically operate in pulse
mode, and are often used to both
engrave, bore or pierce materials.
