The technical problem tackling of laser pointer

The technical problem tackling of laser pointer has achieved a good result.
Through this introduction, powerful confocal microscope has been evident. And other biological technologies (such as immunohistochemistry, in situ hybridization, etc.) match, to further expand its detection range. We use confocal microscopy almost qualitative and quantitative detection of intracellular biochemical composition of any one. Confocal laser scanning microscopy (Confocal laser scanning microscopy) is a high-resolution micro-imaging technology. The quality of laser pointer has been improved more after the technical problem was tackled.
Laser technology is the early 1960s, developed a high-tech, after 40 years of development, from the mechanism of theory, experimental methods to the manufacturing process have gradually matured, the attention by the major military power, the future of military technology is expected to become the most an active area. Important feature of the laser are as follows: high brightness. Laser surface brightness brighter than the sun than ten billion times, this is an ordinary high-brightness light source can not be compared. This kind of laser pointer is the multifunctional type.
Strong directional. Laser emission is almost ideal parallel light beam, it can spread very far and very little divergence, the laser beam a distance of 20 kilometers, almost no divergence, the laser fired at the moon, not the spot to 2 km. People took advantage of this characteristic, accurately measure the distance between the Moon and Earth (384,000 km). Color is good. Different colors, are essentially different wavelengths of light, ordinary light source has a wavelength range of the human eye can sense wavelength is 3800 ~ 7600 angstroms, and a very narrow range of laser wavelength. Monochromatic laser light source spectrum is generally narrower than the times to a million times, is the world's best monochromatic light source. This kind of laser pointer has multiple functions.
Coherence is good. Monochromatic laser is almost ideal, is a good coherent light. The variety of natural and artificial light in space and time is messy, unrelated non-coherent light. As the laser with the above characteristics, the field of laser technology in the military is widely used. The main applications are: laser weapons for anti-enemy heavy weapons and equipment, you need a high energy, high-energy laser weapons or commonly known as laser guns. The U.S. has developed airborne laser gun and car. The powerful laser cannons, hit rate is very high.
