Laser marking on stainless steel A laser engraving machine A laser engraver. A laser engraving machine consists of three main parts: a laser, a controller, and a surface. [2] The laser is a drawing tool: the beam emitted from it allows the controller to trace patterns onto the surface.
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.
Extreme ultraviolet lithography (EUVL, also known simply as EUV) is a technology used in the semiconductor industry for manufacturing integrated circuits (ICs). It is a type of photolithography that uses 13.5 nm extreme ultraviolet (EUV) light from a laser-pulsed tin (Sn) plasma to create intricate patterns on semiconductor substrates.
Recording data using a femtosecond-laser was first proposed and demonstrated in 1996. [1] [14] [15] The storage medium consists of fused quartz, where the spatial dimensions, intensity, polarization, and wavelength are used to modulate data. By introducing gold or silver nanoparticles embedded in the material, their plasmonic properties can be ...
The earliest players employed gas helium–neon laser tubes to read discs and had a red-orange light with a wavelength of 632.8 nm, while later solid-state players used infrared semiconductor laser diodes with a wavelength of 780 nm. In March 1984, Pioneer introduced the first consumer player with a solid-state laser, the LD-700.
