7. Laser Application
Industrial Purpose
Laser light is used to collect the information about
the prefixed prices of various products in shops and
business establishments from the barcode printed on
the product.
lasers are used now for cutting, drilling and
welding of metals and other materials.

15. The Active Medium contains atoms which can
emit light by stimulated emission.
The Excitation Mechanism is a source of
energy to excite the atoms to the proper
energy state.
