This column has a unique hexagonal nano-crystalline structure, it can control the light in the tiny tubes to form a highly effective guidance and control cavity. It can produce at room temperature of about 950 nm wavelength near-infrared laser light in which the spiral form of communication up and down, through the interaction can be optically amplified. The researchers pointed out that the combination of silicon and III-V optoelectronic chips made from single biggest obstacle is that the current industrial production of manufacturing silicon-based materials and manufacturing equipment not compatible with III-V devices. “Let the III-V semiconductors grown on the silicon surface, compatible with silicon manufacturing equipment is the key, but because of the economic and technical reasons, the current silicon electronics production facilities difficult to change, we can and use a CMOS (complementary metal oxide semiconductor, for the manufacture of integrated circuit)-compatible growth process, the successful integration of a silicon chip III-V nano-lasers.   green laser pointer     is a new type of patented electronic product.
Traditional methods III-V semiconductor growth, to 700 degrees Celsius or higher temperatures, this will destroy silicon-based electronic components. The new technology will be able to grow at 400 ° C under high-quality III-V materials, silicon-based electronic components to ensure the normal functioning. “Principal investigator, University of California, Berkeley professor of electrical engineering and computer science ? Connie Chang – Ha Sinan said Zhang – Ha Sinan also noted that the sub-wavelength multi-laser technology will have wide fields of science, including materials science, transistor technology, laser science, optoelectronics and optical physics, for computer, communications, display and optical signal processing and other fields optoelectronics revolution. “Ultimately, we hope to strengthen these laser characteristics of performance, in order to achieve photonic and electronic devices with.  100mW green laser pointer    is especially designed for computer.
Nanolaser human development progress in 1960, the first laser to produce. 40 years later, the laser in terms of its type or its performance has emerged on the colorful splendor of the development. Since the advent of the first ruby laser, followed by gas lasers, various types of solid-state lasers, semiconductor lasers, liquid lasers, excimer lasers, X-ray lasers, free electron lasers, quantum well lasers, quantum dot lasers, soliton lasers have also may be developed. Laser science and technology, rapid development of modern science and technology led to many important applications of the laser, but also led to the development of a variety of new disciplines and to promote the formation of many interdisciplinary. Seamless laser engraved chapter machine parts electric car network company Liaocheng tungsten wire cutter laser engraving machine, however, as human society advances in technology, the laser itself, the pace of development has never stopped.  50mW blue violet laser pointer    has gained increasing popularity in European countries.
“Science” published by the American University of California, Berkeley, M. Huang and P. Yang, who’s “nano-laser UV radiation at room temperature,” claims is the world’s smallest laser. They were first in the sapphire substrate coated with a thickness of 3.5 microns of gold, and then put them in aluminum evaporating dish, in argon and substrate materials will be heated to 880 ~ 905 ° C to generate Zn vapor, resulting in the Zn steam delivered to the substrate, after about 2 to about 10 minutes, hexagonal cross-section of the nanowires can grow to 2 to 10 microns. 20 ~ 150 nm diameter nanowires naturally form a laser cavity. At room temperature for the hexagonal nanowire cross-section sample with Nd: YAG laser fourth harmonic of the laser pump (wavelength 266nm, pulse width of 3ns), the pump laser beam incident angle of 10 degrees focus on nanowires the symmetry axis.   200mW green Laser Pointer    is also popular in other developed countries.
