Semiconductor lasers operate based on stimulated emission of radiation within semiconductor materials. They work on the principles of stimulated emission and using a resonant optical cavity formed by mirrors to produce coherent light. Semiconductor lasers are used in optical storage devices like CDs and DVDs, I/O devices like barcode readers and printers, telecommunications through fiber optic networks, and high-energy applications including gem-cutting and laser fusion.

3. What is the semiconductor
laser
 Semiconductor
LASER<it is a LASER in
which the the laser
based upon the
optical gain media
that achieved by the
stimulated emission
at an interband under
the transition under
the condition of a
high carrier density in
the conduction band:

4. WORKING PRINCIPLE
 It is work on the principle of the
Stimulated emission and Resonant optical
cavity.

5. 2->Resonant Optical Cavity=It is an
arrangement of mirrors that forms
a standing wave cavity resonator for light
waves.
