Vor 5 Tagen · Led research into novel lasers and semiconductor devices. During his tenure, Smith was awarded dozens of patents and eventually headed the VLSI device department. George E. Smith shared the 2009 Nobel Prize in Physics with Willard Boyle for "the invention of an imaging semiconductor circuit—the CCD sensor , which has become an ...
20. Mai 2024 · This study not only represents an important step in the journey of SE UV laser development but, more importantly, it lays the ground for SE lasers with lasing wavelength on demand, broadly from NIR to UV. KEYWORDS: surface-emitting laser. lasing wavelength on demand. electrical injection.
Vor 5 Tagen · Techniques have been developed to produce nanotubes in sizeable quantities, including arc discharge, laser ablation, chemical vapor deposition (CVD) and high-pressure carbon monoxide disproportionation (HiPCO).
18. Mai 2024 · Eine Laserdiode (auch Halbleiterlaser) ist ein mit der Leuchtdiode (LED) verwandtes Halbleiter -Bauteil, das jedoch Laserstrahlung erzeugt. Laserdiode im 5,6-mm-Gehäuse, wie es unter anderem in CD-Laufwerken verwendet wird (Größenvergleich: Münze mit 19 mm Durchmesser)
13. Mai 2024 · Lasers made from semiconductors are small, efficient solid-state lasers that amplify light through stimulated emission, emitted at wavelengths ranging from 600 nanometers to 1.6 micrometers in the near-infrared. Advantages of Semiconductor Lasers.
13. Mai 2024 · Laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation. The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths.
17. Mai 2024 · An integrated high-energy laser that combines a passively Q -switched laser cavity based on a silicon-nitride photonic integrated circuit with an optically pumped gain layer consisting of...
