The retail price of Laser Pointer should be determined

The retail price of Laser Pointer should be determined as soon as possible.
Laser technology and industrial development will support and promote high-speed, broadband, optical communication and mass communication networks, will lead to a revolution in lighting technology, compact, reliable, long life, energy-saving semiconductor (LED) will dominate the market, in addition to the launch a wide variety of optoelectronic consumer products (such as VCD, D VD, digital cameras, new color TVs, handheld electronic products, computers, smart phones, hand-held audio playback device, photography, projection and imaging, office automation equipment such as optical laser printing, faxing and copying etc.) and display the new information technology products (such as CRT, LCD and PDP, FED, OEL flat panel displays, etc.) and into people's daily lives. The retail price of Laser Pointer will be much higher than whole price.
Since the 20th century, the laser is the second atomic energy, computers, semiconductors, after another major scientific and technological inventions. There is adequate theoretical preparation and production practice needs in the context of laser technology came into being. It came on to obtain an unusually rapid development. Laser in the field of modern communication with a wide range of applications. It is the expansion of communication capacity, ease traffic congestion band, to improve communication security and other aspects play a very important role. The exhibition of Laser Pointer will be held soon.
May 16, 1960, the world's first laser - Ruby laser emits a beam of light magic, it's called "laser." The name of the original Chinese is called "laser", "les" is its English transliteration of the name of LASER. LASER is the English word "light amplification by stimulated emission of radiation" in the acronym. What is called "stimulated emission"? He based the great scientist Albert Einstein in 1916 proposed a new set of theories. The theory is that the atoms in the composition of the material, there are different number of particles (electrons) in different energy levels, in the high level of particles excited by a photon, will jump from a high energy level (transition) to the low level. Various types of Laser Pointer will be exhibited in the exhibition of Laser Pointer .
At this time it will emit light with excitation light of the same nature, and in certain conditions, can stimulate the emergence of a low-light glare of a phenomenon.
