Joel Solon Spira (March 1, 1927 – April 8, 2015) was an American inventor, entrepreneur, and business magnate.. He invented a version of the light-dimmer switch for use in homes around the United States and led his Lutron Electronics Company into the production of lighting controllers.
Holmium YAG (Ho:YAG) laser 2.1 μm Flashlamp, laser diode Tissue ablation, kidney stone removal, dentistry. Chromium ZnSe (Cr:ZnSe) laser 2.2 - 2.8 μm Other laser (Tm fiber) MWIR laser radar, countermeasure against heat-seeking missiles etc. Cerium-doped lithium strontium (or calcium) aluminum fluoride (Ce:LiSAF, Ce:LiCAF) ~280 to 316 nm
Nanowire lasers can be grown site-selectively on Si/SOI wafers with conventional MBE techniques, allowing for pristine structural quality without defects. Nanowire lasers using the group-III nitride and ZnO materials systems have been demonstrated to emit in the visible and ultraviolet, however infrared at the 1.3–1.55 μm is important for telecommunication bands.

A disk laser configuration presented in 1992 at the SPIE conference. [1] One type of solid-state laser designed for good power scaling is the disk laser (or "active mirror" [1]). Such lasers are believed to be scalable to a power of several kilowatts from a single active element in continuous-wave operation. [2]
Specctra is a commercial PCB auto-router originally developed by John F. Cooper and David Chyan of Cooper & Chyan Technology, Inc. (CCT) in 1989. [2] The company and product were taken over by Cadence Design Systems in May 1997. [3] [2] [4] Since its integration into Cadence's Allegro PCB Editor, the name of the router is Allegro PCB Router ...
JST manufactures numerous series (families) and pitches (pin-to-pin distance) of connectors. [ 2 ] [ 3 ] JST connectors are used in many types of products, and commonly used by electronics hobbyists and consumer products for rechargeable battery packs, battery balancers , battery eliminator circuits , 3D printers , and radio controlled servos .
A laser diode (LD, also injection laser diode or ILD or semiconductor laser 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. [1]: 3
A technique that is commonly employed in these devices is cascading, first proposed in 1994: [5] The "first-order" laser light that is generated from the pump light in a single frequency-shifting step remains trapped in the laser resonator and is pushed to such high power levels that it acts itself as the pump for the generation of "second ...
