Diode Laser Lenses
An injection laser diode (ILD), diode laser, or laser diode (LD), is a semiconductor device similar to a light-emitting diode in which a laser beam is created at the diode’s junction. Laser diodes can directly convert electrical energy into light. Driven by voltage, the doped p-n-transition allows for recombination of an electron [...]
To answer the question, what is laser technology and where it can be used, it’s important to understand exactly to what the term laser refers. The term itself originated as an acronym ‘light amplification by stimulated emission of radiation’. in other words, ‘laser’ is a device that emits light through [...]
Laser diode collimators are used to collimate the highly divergent beam that is emitted by a laser diode. It consists of a laser diode holder, a collimating lens holder, and a high numerical aperture (NA) collimating lens, with a focal length f. The lens is housed in a threaded receptacle [...]
The use of medical lasers is not a new technique employed in hospitals, but there are new applications being developed with regularity that assist with drug delivery, gene therapy, nerve repair, dentistry and oncology. In 1967 a researcher in Budapest, Hungary recognized that a ruby laser could stimulate faster hair [...]
Cutting through metal generally requires the use of crystals for amplification or focus but a new company in Wilmington, MA called TeraDiode has developed the first metal-cutting machine that uses only laser diodes. The new machine is known as Terablade. It is estimated to be 40% more efficient and less [...]
