2. Nd:YAG laser - Wikipedia

   en.wikipedia.org/wiki/Nd:YAG_laser

   Nd:YAG (neodymium-doped yttrium aluminum garnet; Nd:Y 3 Al 5 O 12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant , neodymium in the +3 oxidation state, Nd(III), typically replaces a small fraction (1%) of the yttrium ions in the host crystal structure of the yttrium aluminum garnet (YAG), since the two ions are ...

3. 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 ...

4. 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.

5. List of laser types - Wikipedia

   en.wikipedia.org/wiki/List_of_laser_types

   Neodymium-doped yttrium calcium oxoborate Nd:Y Ca 4 O(BO 3) 3 or simply Nd:YCOB ~1.060 μm (~530 nm at second harmonic) laser diode Nd:YCOB is a so-called "self-frequency doubling" or SFD laser material which is both capable of lasing and which has nonlinear characteristics suitable for second harmonic generation. Such materials have the ...

6. Pulse-forming network - Wikipedia

   en.wikipedia.org/wiki/Pulse-forming_network

   A pulse-forming network for an Nd:YAG laser rangefinder The Shiva Star device at Air Force Research Laboratory, USA, which generates pulsed power for high-energy fusion power experiments. Each of the 6 radial arms is a pulse-forming line delivering a pulse of energy to the center, whose capacitors store a total of 10 MJ of energy and can create ...

7. Titanium-sapphire laser - Wikipedia

   en.wikipedia.org/wiki/Titanium-sapphire_laser

   Ti:sapphire oscillators are normally pumped with a continuous-wave laser beam from an argon or frequency-doubled Nd:YVO4 laser. Typically, such an oscillator has an average output power of 0.4 to 2.5 watts (5.7 to 35 nJ in each laser pulse for the 70 MHz repetition rate).

8. Active laser medium - Wikipedia

   en.wikipedia.org/wiki/Active_laser_medium

   Laser rods (from left to right): Ruby, Alexandrite, Er:YAG, Nd:YAG The active laser medium (also called a gain medium or lasing medium ) is the source of optical gain within a laser . The gain results from the stimulated emission of photons through electronic or molecular transitions to a lower energy state from a higher energy state previously ...

9. 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 ]
