2. Laser engraving - Wikipedia

   en.wikipedia.org/wiki/Laser_engraving

   Laser engraving metal plates are manufactured with a finely polished metal, coated with an enamel paint made to be "burned off". At levels of 10 to 30 watts, excellent engravings are made as the enamel is removed quite cleanly. Much laser engraving is sold as exposed brass or silver-coated steel lettering on a black or dark-enamelled background.

3. List of laser types - Wikipedia

   Flashlamp, laser diode Used in extremely high-power (terawatt scale), high-energy multiple beam systems for inertial confinement fusion. Nd:Glass lasers are usually frequency tripled to the third harmonic at 351 nm in laser fusion devices. Titanium sapphire (Ti:sapphire) laser 650-1100 nm Other laser Spectroscopy, LIDAR, research.

4. Laser cutting - Wikipedia

   en.wikipedia.org/wiki/Laser_cutting

   The CO 2 laser is suited for cutting, boring, and engraving. The neodymium (Nd) and neodymium yttrium-aluminium-garnet lasers are identical in style and differ only in the application. Nd is used for boring and where high energy but low repetition are required. The Nd:YAG laser is used where very high power is needed and for boring and engraving.

5. 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 ...

6. 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.

7. Fiber laser - Wikipedia

   en.wikipedia.org/wiki/Fiber_laser

   Due to the introduction of large mode area (LMA) fibers as well as continuing advances in high power and high brightness diodes, continuous-wave single-transverse-mode powers from Yb-doped fiber lasers have increased from 100 W in 2001 to a combined beam fiber laser demonstrated power of 30 kW in 2014. [14] High average power fiber lasers ...
