An acronym for Light Amplification by the Stimulated Emission of Radiation, lasers are a focused beam which has many applications in today's world. See the main Laser article for a history of this technology
Subcategories
- Gas lasers - a laser in which the electric current is discharged through a gas to produce coherent light
- Laser applications - the uses and benefits of lasers
- Laser excitation - using lasers to excite isotopes to induce separation or for other purposes
- Laser transitions - or amplifier transition, a transition between two electronic levels of some laser-active ion
- Pump lasers - lasers that use energy transfer from an external source into the gain medium of the laser
- Quantum well lasers - a laser diode in which the active region of the device is narrow enough to cause quantum confinement
- Ring lasers - a laser in which the laser cavity has the shape of a ring
- Semiconductor lasers - lasers based on a semiconductor gain media, where optical gain is achieved by stimulated emission at an interband transition
- Solid-state lasers - a laser that uses a gain medium that is solid rather than liquid or gas
- Surface emitting lasers - a laser in which light propagates in the direction perpendicular to the surface, a type of semiconductor laser
