ENGINEERING
APPLICATIONS OF LASER
1. Property: It has
Narrow band width and angular spread
Due
to this property, it is used in communications, to transmit thousands of
programs, transmitting signals from longer distances called as long haul
communication system.
2. Property: It is not
absorbed by water
Hence
they are used in underwater communication between the submarines, which is very
useful for military.
3. Property: It has
high penetrating power
(a)
It is useful to (a) blast holes in diamonds and hard steels.
(b)
It is used in drilling minute holes in cellwalls of human body.
(c)
Using lasers, Cancer treatment can also be done.
(d)
It is used to destroy tumors.
4. Property:
Directionality
(a)
It is useful in the production of laser gun and laser torches.
(b)
It is used to do micro surgery and blood less operations.
(c)
It is further used in laser printing and in computer storage devices.
5. Property: Highly
intense
Because
of its high intensity and directionality, they are very useful in endoscopic
applications in the medical field.
6. Apart
from these applications, they are used in recent engineering applications like
(i)
Material processing, (ii) CD‒ROM, (iii) Holography etc.
