semiconductor laser diode
11Diode-pumped solid-state laser — A frequency doubled green laser pointer, showing internal construction. Cells and electronics lead to a laser head module (see lower diagram) This contains a powerful 808 nm IR diode laser that pumps a Nd:YVO4 laser crystal, that in turn outputs… …
12laser — /lay zeuhr/, n. Physics. a device that produces a nearly parallel, nearly monochromatic, and coherent beam of light by exciting atoms to a higher energy level and causing them to radiate their energy in phase. Also called optical maser. [1955 60; …
13Laser construction — A laser is constructed from three principal parts:*An energy source (usually referred to as the pump or pump source ), *A gain medium or laser medium , and *Two or more mirrors that form an optical resonator . Pump sourceThe pump source is the… …
14Vertical-cavity surface-emitting laser — The vertical cavity surface emitting laser (VCSEL; [v ɪxl] ) is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge emitting semiconductor lasers (also in plane lasers)… …
15Blue laser — The term blue laser is frequently applied to semiconductor laser diode based on gallium nitride. These new devices have applications in many areas ranging from optoelectronic data storage at high density to medical applications. Thanks to prior… …
16Laser soldering — is a technique where a 30 50 W laser is used to melt and solder an electrical connection joint. Diode laser systems based on semiconductor junctions are used for this purpose. [cite web|title=Laser Solutions for… …
17diode — /duy ohd/, n. Electronics. a device, as a two element electron tube or a semiconductor, through which current can pass freely in only one direction. [1919; DI 1 + ODE2] * * * Electronic device that has two electrodes (anode and cathode) and that… …
18Laser interstitial thermal therapy — The term laser interstitial thermal therapy (LITT, also referred to as laser induced interstitial thermotherapy or laser induced thermotherapy or interstitial laser therapy) is a surgical procedure in which destruction of soft tissues in the body …
19semiconductor — /sem ee keuhn duk teuhr, sem uy /, n. 1. a substance, as silicon or germanium, with electrical conductivity intermediate between that of an insulator and a conductor: a basic component of various kinds of electronic circuit element (semiconductor …
