The application of lasers in the field of communications, the development of optical fiber communications industry, fiber optic communications have developed rapidly in the military, civil, and it can work in the tens of MHz shortwave, ultrashort wave band can also work in the microwave band changed over the past communications capacity limited outlook. Based on MEMS technology, wavelength tunable lasers is considered to be the best choice for optical fiber access networks, because of their rapid, low-power, the advantages of a large adjustment range, has been gradually get the recognition and pursuit of the important optical communication research institutions. Digital optical fiber communication using lasers instead of analog fiber optic communications lasers, temperature control, pre-distortion compensation circuit, such as linear compensation method, as well as in the input AGC, fixed attenuators, dynamic range compensation. The drawing draft of Green Laser Pointer 5MW is the vital and important process.
Digital optical fiber communication has been greatly improved linearity and dynamic range of the laser to achieve analog fiber optic communications, laser level can be applied to the band of short, ultra short wave and microwave analog optical fiber communication. Atmospheric laser communication is based on the atmosphere as a transmission medium of communication, laser appear first developed as a means of communication. Atmospheric absorption and dispersion makes use of laser communication with some boundaries on the ground, but the use of gas lasers to create good climate at night to transmit information of hundreds of kilometers to several tens of kilometers during the day and transmit information in a good climate devices. Optical communication can not only send phone, and can transmit data, fax, TV and video telephony. That is according to the specific requirements of laser pointers.
Thus can choose exactly in the treatment of the lesion. Laser with its unique advantages to solve the problem of a lot of traditional medicine. Zumba Fitness DVD The laser treatment was first used in ophthalmology for retinal detachment, retinal vascular lesions, iridotomy, glaucoma, such as a large number of ophthalmic disorders can use laser treatment. Laser scalpel with less blood loss, can reduce bacterial infection and other advantages. Laser and traditional Chinese medicine acupuncture combined with the formation of "light needle", analgesia, asthma, enuresis, hypertension, have a certain effect. Modern medicine, laser technology provides a "divine", able to treat more than 100 kinds of medicine, surgery, ophthalmology, skin, cancer and ENT diseases. It is based on the good advice and strict requirement of laser pointers.
The low-intensity medical lasers photobiomodulation (photobiomodulation PBM) to regulate cell, organ or tissue function. PBM is a low-intensity monochromatic light or laser (10w intensity the monochromatic lightor a laser irradiation, LIL) on biological systems, a non-invasive non-thermal photochemical regulatory role. With the molecular resonance effect of the laser wavelength is called the characteristic wavelength of the molecule. Endogenous photosensitizer characteristic wavelengths in the visible region. Membrane proteins characteristic wavelength than the long-wave UV (320 ~ 400nm) (the ultraviolet A.UVA) short. The uL role of the basic unit of the object cell mediated PBM two pathways: the endogenous photosensitizer mediated by the specific pathway of PBM. Here will introduce a new type of laser pointers.
