2. Nd:YAG laser - Wikipedia

   en.wikipedia.org/wiki/Nd:YAG_laser

   However, there are also transitions near 946, 1120, 1320, and 1440 nm. Nd:YAG lasers operate in both pulsed and continuous mode. Pulsed Nd:YAG lasers are typically operated in the so-called Q-switching mode: An optical switch is inserted in the laser cavity waiting for a maximum population inversion in the neodymium ions before it opens. Then ...

3. Q-switching - Wikipedia

   en.wikipedia.org/wiki/Q-switching

   Q-switching, sometimes known as giant pulse formation or Q-spoiling, [1] is a technique by which a laser can be made to produce a pulsed output beam. The technique allows the production of light pulses with extremely high peak power, much higher than would be produced by the same laser if it were operating in a continuous wave (constant output) mode.

4. List of laser types - Wikipedia

   en.wikipedia.org/wiki/List_of_laser_types

   One of the most common high-power lasers. Usually pulsed (down to fractions of a nanosecond), dental laser: Nd:YAP laser (yttrium aluminium perovskite) 1.0646 μm [7] Flashlamp, laser diode: Surgery, tattoo removal, hair removal, research, pumping other lasers (combined with frequency doubling to produce a green 532 nm beam) Nd:Cr:YAG laser

5. Laser beam welding - Wikipedia

   en.wikipedia.org/wiki/Laser_beam_welding

   Nd:YAG lasers can operate in both pulsed and continuous mode, but the other types are limited to pulsed mode. The original and still popular solid-state design is a single crystal shaped as a rod approximately 20 mm in diameter and 200 mm long, and the ends are ground flat. This rod is surrounded by a flash tube containing xenon or krypton ...

6. Pulsed laser - Wikipedia

   en.wikipedia.org/wiki/Pulsed_laser

   Pulsed Nd:YAG and Er:YAG lasers are used in laser tattoo removal and laser range finders among other applications. Pulsed lasers are also used in soft-tissue surgery. When a laser beam comes into contact with soft-tissue, one important factor is to not overheat surrounding tissue, so necrosis can be prevented. [3]

7. Photodisruption - Wikipedia

   en.wikipedia.org/wiki/Photodisruption

   This means the area highlighted by the HeNe laser is not precisely the area being affected Nd:YAG laser, and therefore some surgical lasers have an added adjustment to compensate. [2] The first successful use of photodisruption was in 1972, on a case of trabecular meshwork. [1]

8. Laser drilling - Wikipedia

   en.wikipedia.org/wiki/Laser_drilling

   [citation needed] A Q-switched Nd:YAG laser normally has pulse duration in the order of nanoseconds, peak power on the order of ten to hundreds of MW/cm 2, and a material removal rate of a few micrometers per pulse. A flash lamp pumped Nd:YAG laser normally has a pulse duration on the order of hundreds of microseconds to a millisecond, peak ...

9. Solid-state laser - Wikipedia

   en.wikipedia.org/wiki/Solid-state_laser

   Laser rods (from left to right): Ruby, alexandrite, Er:YAG, Nd:YAG. A solid-state laser is a laser that uses a gain medium that is a solid, rather than a liquid as in dye lasers or a gas as in gas lasers. [1] Semiconductor-based lasers are also in the solid state, but are generally considered as a separate class from solid-state lasers, called ...
