Direct laser engraving of flexographic printing cylinders and plates has been an established process since the 1970s. This first began with the use of a carbon dioxide laser used to selectively ablate or evaporate a variety of rubber plate and sleeve materials to produce a print-ready surface without the use of photography or chemicals.
CO 2 lasers are used in spectroscopy [18] and the Silex process to enrich uranium. In semiconductor manufacturing, CO 2 lasers are used for extreme ultraviolet generation. The Soviet Polyus was designed to use a megawatt carbon-dioxide laser as an in-orbit weapon to destroy SDI satellites.
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.
Flashlamp, laser diode Mostly used for pulsed pumping of certain types of pulsed Ti:sapphire lasers, combined with frequency doubling. Neodymium-doped yttrium orthovanadate (Nd:YVO 4) laser 1.064 μm laser diode Mostly used for continuous pumping of mode-locked Ti:sapphire or dye lasers, in combination with frequency doubling. Also used pulsed ...
Trotec Laser is an international manufacturer of advanced laser technology for laser cutting, laser engraving and laser marking. The company was founded in 1997, [ 1 ] branching off from a research and development department within its parent company Trodat .
He developed the carbon dioxide laser in 1963; [1] it is now widely used in industry for cutting and engraving a wide range of materials like plastic and wood. Because the atmosphere is quite transparent to infrared light, CO 2 lasers are also used for military rangefinding using LIDAR techniques.
