2. Laser diode - Wikipedia

   en.wikipedia.org/wiki/Laser_diode

   A laser diode ( LD, also injection laser diode or ILD or semiconductor laser or diode laser) is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode's junction. [1] : 3.

4. Vertical-cavity surface-emitting laser - Wikipedia

   en.wikipedia.org/wiki/Vertical-cavity_surface...

   The vertical-cavity surface-emitting laser ( VCSEL / ˈvɪksəl /) is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge-emitting semiconductor lasers (also called in-plane lasers) which emit from surfaces formed by cleaving the individual chip out of a wafer.

5. Semiconductor laser theory - Wikipedia

   en.wikipedia.org/wiki/Semiconductor_laser_theory

   Semiconductor lasers (660nm, 532nm, 405nm) Semiconductor lasers or laser diodes play an important part in our everyday lives by providing cheap and compact-size lasers. They consist of complex multi-layer structures requiring nanometer scale accuracy and an elaborate design. Their theoretical description is important not only from a fundamental ...

6. Distributed-feedback laser - Wikipedia

   en.wikipedia.org/wiki/Distributed-feedback_laser

   A distributed-feedback laser ( DFB) is a type of laser diode, quantum-cascade laser or optical-fiber laser where the active region of the device contains a periodically structured element or diffraction grating. The structure builds a one-dimensional interference grating ( Bragg scattering ), and the grating provides optical feedback for the laser.

7. Diode-pumped solid-state laser - Wikipedia

   en.wikipedia.org/wiki/Diode-pumped_solid-state_laser

   A diode-pumped solid-state laser ( DPSSL) is a solid-state laser made by pumping a solid gain medium, for example, a ruby or a neodymium-doped YAG crystal, with a laser diode . DPSSLs have advantages in compactness and efficiency over other types, and high power DPSSLs have replaced ion lasers and flashlamp-pumped lasers in many scientific ...
