3. • LASER is the acronym for Light Amplified Stimulated
Emission of Radiation
• Emits light through a process of optical amplification based
on the stimulated emission of electromagnetic radiation.
• Coherent, monochromatic, directional and high power laser
beam is used.
• Types of LASER : (1) Gas Laser
(2) Excimer Laser
(3) Solid State Laser

4. • In this process LASER is
focused on work piece by
optical lence.
• Uses light energy from a laser
to remove material by
vaporization.
• Thermal and Optical energy is
used in this process.
• Light beam pulsed so that the
released energy results in an
impulse against the work
surface, producing
evaporation and melting

5. • Cutting starts by drilling a
hole by moving beam
• Cutting speed depends
on material and thickness
• Both pulsed and
continuous laser is used
• Thickness ranges from
0.5-1 inch
• Used for cutting complex
geometry and for clean
cutting operation

8. • Non-contact
• No solvent chemical
• Machining of Hard & soft material .
• Flexibility
• Fully automated

9. • Requires specially trained operators
• Not for mass metal removal
processes
• This process is very slow.
• Expensive equipment
• Consumes much energy
