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.

What is the difference between solid state laser and semiconductor laser?
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.
What is the principle working construction of junction laser?
the junction lasers principle is like a normal laser but a specific junction will activate it. This is good because if you are away from the where the laser is then you can activate it without being there.
Is a diode laser a nd. yag laser?
No, a diode laser and an Nd:YAG laser are two different types of lasers. A diode laser uses a diode as the laser medium and is commonly used for various applications such as hair removal and skin treatments. On the other hand, an Nd:YAG laser uses neodymium-doped yttrium aluminum garnet as the laser medium and is often used for medical and cosmetic procedures, as well as in industrial applications.
Why is only one colour produced in a Laser Beam?
The color of a laser beam is determined by the type of material used in the laser, such as a specific gas or semiconductor. These materials emit light at a specific wavelength, resulting in a single-color beam. Additional optics can be used to combine different lasers to produce multiple colors in laser light shows.
Who was the inventor of the laser?
Albert Einstein laid the foundation for the laser in 1917. The principle was found by H.Charles Townes. And Maiman found it in1960.
Is dye or semiconductor or gas or excimer laser used in laser printers?
Semiconductor laser
What are semiconductor diode laser describe with energy band diagram the construction and working of a semiconductor diode laser?
construction and working of semiconductor laser
What is semiconductor laser?
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.
Does semiconductor lasers and laser diodes are similar?
Semiconductor lasers are made with laser diodes, with added circuitry to measure and regulate the diode current/output.
What is the difference between solid state laser and semiconductor laser?
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.
What kind of gas is in a red LASER diode?
None, LASER diodes are solid state semiconductor devices.
What determines if a laser is solid state gas liquid or semiconductor?

What are laser rangefinders used for?
A laser rangefinder uses a laser to determine the distance to an object. The principle used is the time of flight principle based on the speed of light.
What has the author S L Palfrey written?
S. L. Palfrey has written: 'Monolithic narrow-linewidth InGaAsP semiconductor laser for coherent optical communications' -- subject(s): Semiconductor lasers, Laser communication systems
Who invented the first semiconductor laser used in CD players?
Robert Hall invented the first semiconducter laser for CD players :)
What is a laser diode?
It's what makes the light !
Difference between light emitting diode and laser?
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.
