A semiconductor laser is a type of laser which utilizes a semiconductor as its Photon source, rather than a gas (Argon, CO2, Etc...) laser which uses inert gas as an active medium.
Many physicists and engineers consider a semiconductor laser a type of "Solid-State" or "Two-State" LASER.
p-type semiconductor A semiconductor that is missing electrons is called an electron hole.
The motto of Cypress Semiconductor is 'Perform'.
A: It not a semiconductor at all but it is a very Good conductor.
the impurity add here is 1 atom of per million atoms of semiconductor.......
it is like p type semiconductor because when adding impurity its conductivity decreases
Semiconductor laser
construction and working of semiconductor laser
Semiconductor lasers are made with laser diodes, with added circuitry to measure and regulate the diode current/output.
LASER is Light amplification by stimulated emission of radiation. As far as I have understood, Solid State laser is a macroscopic form of diode laser. Thus a small semiconductor diode is similar to a solid state laser except for the mechanism of lasing and size.
None, LASER diodes are solid state semiconductor devices.

Semiconductor lasers are diodes which are electrically pumped. Recombination of electrons and holes created by the applied current introduces optical gain. Reflection from the ends of the crystal form an optical resonator, although the resonator can be external to the semiconductor in some designs.

Robert Hall invented the first semiconducter laser for CD players :)
It's what makes the light !
LEDs, known as light emitting diodes, are comprised of two lead semiconductor light sources. Laser transmitters, also known as laser diodes are comprised of an electrically charged semiconductor laser.
