2. Bubblegram - Wikipedia

   en.wikipedia.org/wiki/Bubblegram

   Bubblegram. A laser glass sculpture of a caffeine molecule. A bubblegram (also known as laser crystal, Subsurface Laser Engraving, 3D crystal engraving or vitrography) is a solid block of glass or transparent plastic that has been exposed to laser beams to generate three-dimensional designs inside. The image is composed of many small points of ...

3. Nd:YAG laser - Wikipedia

   en.wikipedia.org/wiki/Nd:YAG_laser

   Nd:YAG laser. Nd:YAG (neodymium-doped yttrium aluminum garnet; Nd:Y3Al5O12) 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 ...

4. Laser engraving - Wikipedia

   en.wikipedia.org/wiki/Laser_engraving

   Laser marked electronic part. Laser engraving is the practice of using lasers to engrave an object. The engraving process renders a design by physically cutting into the object to remove material. The technique does not involve the use of inks or tool bits that contact the engraving surface and wear out, giving it an advantage over alternative ...

5. Glass cutter - Wikipedia

   en.wikipedia.org/wiki/Glass_cutter

   A glass cutter is a tool used to make a shallow score in one surface of a piece of glass (normally a flat one) that is to be broken in two pieces, for example to fit a window. The scoring makes a split in the surface of the glass which encourages the glass to break along the score. [1] This is not to be confused with the tools used to make cut ...

   Ytterbium: 2 O 3 (glass or ceramics) laser 1.03 μm Laser diode Ultrashort pulse research, [9] Ytterbium-doped glass laser (rod, plate/chip, and fiber) 1. μm Laser diode Fiber version is capable of producing several-kilowatt continuous power, having ~70-80% optical-to-optical and ~25% electrical-to-optical efficiency.

7. Carbon-dioxide laser - Wikipedia

   en.wikipedia.org/wiki/Carbon-dioxide_laser

   The carbon-dioxide laser (CO2 laser) was one of the earliest gas lasers to be developed. It was invented by Kumar Patel of Bell Labs in 1964 [1] and is still one of the most useful types of laser. Carbon-dioxide lasers are the highest-power continuous-wave lasers that are currently available. They are also quite efficient: the ratio of output ...
