  2. 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 ...

    en.wikipedia.org/wiki/Blue_laser

    Blue DPSS laser pointers, initial availability around 2006, have the same basic construction as DPSS green lasers. They most commonly emit light at 473 nm, which is produced by frequency doubling of 946 nm laser radiation from a diode-pumped Nd:YAG or Nd:YVO4 crystal. [24]

    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

  5. List of laser applications - Wikipedia

    en.wikipedia.org/wiki/List_of_laser_applications

    Diode lasers are used as a lightswitch in industry, with a laser beam and a receiver which will switch on or off when the beam is interrupted, and because a laser can keep the light intensity over larger distances than a normal light, and is more precise than a normal light it can be used for product detection in automated production.

  6. Laser engraving - Wikipedia

    en.wikipedia.org/wiki/Laser_engraving

    The more popular SSLE engraving machines use the Diode Pumped Solid State or DPSS laser process. The laser diode, the primary component which excites a pulsed solid state laser, can easily cost one third of the machine itself and functions for a limited number of hours, [15] although a good quality diode can last thousands of hours.

    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.

  9. Laser pointer - Wikipedia

    en.wikipedia.org/wiki/Laser_pointer

    Red (635 nm), blueish violet (445 nm), and green (520 nm) laser pointers. A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.
