Controllable fluid dynamics. For about ten years now, application of lasers seems to be most attractive, after experiments had been done using compressed gas or using piezoelectric devices to generate the necessary force.

A laser diode (LD, also injection laser diode or ILD, or diode laser) is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode's junction. Driven by voltage, the doped p–n-transition allows for recombination of an … Visa mer A laser diode is electrically a PIN diode. The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectively. While … Visa mer The simple laser diode structure, described above, is inefficient. Such devices require so much power that they can only achieve … Visa mer Laser diodes are numerically the most common laser type, with 2004 sales of approximately 733 million units, as compared to 131,000 of other types of lasers. Visa mer • Collimating lens • Laser safety • List of laser articles • Superluminescent diode Visa mer As early as 1953 John von Neumann described the concept of semiconductor laser in an unpublished manuscript. Following theoretical treatments of M.G. Bernard, G. … Visa mer Laser diodes have the same reliability and failure issues as light emitting diodes. In addition they are subject to catastrophic optical damage (COD) … Visa mer Visible light • 405 nm: InGaN blue-violet laser, in Blu-ray Disc and HD DVD drives • 445–465 nm: InGaN blue laser multimode diode recently introduced (2010) for use in mercury-free high-brightness data projectors Visa mer Webbstarted to develop high power pumping laser for fiber am - plifier from the early 90’s based on the technology devel - oped for 1.3 µm FP laser. 3-2 Fiber amplifier pumping lasers Two types of pumping lasers, 1.48 µm laser composed on InP and 0.98 µm laser composed on GaAs are used for EDFA.

Fabrication of multimode injection lasers with a single or small number of lateral modes is achieved by the use of stripe geometry. These devices are often called gain-guided lasers. The constriction of the current flow to the stripe is realized in the structure either by implanting the regions ... filey properties enfield reviews
