2. Laser diode - Wikipedia

   en.wikipedia.org/wiki/Laser_diode

   The laser diode chip removed and placed on the eye of a needle for scale A laser diode with the case cut away. The laser diode chip is the small black chip at the front; a photodiode at the back is used to control output power. SEM (scanning electron microscope) image of a commercial laser diode with its case and window cut away. The anode ...

   Flashlamp, laser diode: Periodontal scaling, dental laser, skin resurfacing Neodymium YLF solid-state laser 1.047 and 1.053 μm Flashlamp, laser diode Mostly used for pulsed pumping of certain types of pulsed Ti:sapphire lasers, combined with frequency doubling. Neodymium-doped yttrium orthovanadate (Nd:YVO 4) laser 1.064 μm laser diode

4. Laser pointer - Wikipedia

   en.wikipedia.org/wiki/Laser_pointer

   The low-cost availability of infrared (IR) diode laser modules of up to 1000 mW (1 watt) output has created a generation of IR-pumped, frequency doubled, green, blue, and violet diode-pumped solid-state laser pointers with visible power up to 300 mW. Because the invisible IR component in the beams of these visible lasers is difficult to filter ...

5. Laser - Wikipedia

   However, due to the cost and potential dangers, this is an uncommon hobby. Some hobbyists salvage laser diodes from broken DVD players (red), Blu-ray players (violet), or even higher power laser diodes from CD or DVD burners. [128] Hobbyists have also used surplus lasers taken from retired military applications and modified them for holography ...

6. Diode-pumped solid-state laser - Wikipedia

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

   High power lasers use a single crystal, but many laser diodes are arranged in strips (multiple diodes next to each other in one substrate) or stacks (stacks of substrates). This diode grid can be imaged onto the crystal by means of a lens. Higher brightness (leading to better beam profile and longer diode lifetimes) is achieved by optically ...

7. Quantum well laser - Wikipedia

   en.wikipedia.org/wiki/Quantum_well_laser

   A quantum-well laser is a laser diode in which the active region of the device is so narrow that quantum confinement occurs. Laser diodes are formed in compound semiconductor materials that (quite unlike silicon ) are able to emit light efficiently.
