Theuse of this laser material can be said to be a most meaningful we long days,it's now the day we can face up to the question is we in the use of our laserin the process of unfamiliar and variety of laser by misunderstanding. In fact,in our laser protective window looks like we present day development, mostpeople are lack of clarity about the laser, laser application is indeed veryimportant, but should use the reserved by laser, we should at the same timeusing laser laser equipment data using laser protective window good protectionto the laser.
It is an artificial, special type of nonionizing radiation, with high brightness, direction and good qualitycharacteristics, such as good. Widely used in industry, agriculture, nationaldefense, medical treatment and scientific research.
Onthe basis of the laser emission spectrum, divided into infrared, visible lightand ultraviolet laser and the newly developed X, 7 ray laser; because the laseroutput method is not the same as a continuous wave laser, pulse wave and longpulse laser, and the giant pulse and ultrashort pulse laser. The use of laserincludes laser drilling, the industry cut and welding; for laser radar, laser communication,laser ranging, laser guidance, laser collimation in military and space work;medicine for the treatment of Ophthalmology, surgery, Department of oncology,skin and other diseases; research in life science and nuclear physics thecategory, also have a wide range of applications.
Theinteraction between laser and biological arrangement is mainly characterized bythermal effect, photochemical effect, mechanical pressure, effect andelectromagnetic field effect. The degree of laser injury and damage to humanarrangement, first depends on the wavelength of the laser light source, type,transmission method, the incident point of view, radiation intensity, exposuretime and biological characteristics and spot size arrangement. Laser damage tothe human body's target organs primarily for the eyes and skin.
Laseris one of the important and not in our day, but it still can not be ignored inthe use of inappropriate damage, especially laser damage to the human body.Laser burns are not the same as the general burns but the kind of norehabilitation effect of the most severe damage method, we can expect this typeof laser can clearly recognize the double-edged sword. Laser effect despitelarge, but in the use of good defense is always wrong.
