What's the diode laser products?and the function of diode laser peoducts?
Diode laser products is a diode is a two-terminal electronic component with asymmetric transfer characteristic, with low (ideally zero) resistance to current flow in one direction, and high (ideally infinite) resistance in the other. A semiconductor diode, the most common type today, is a crystalline piece of semiconductor material with a p-n junction connected to two electrical terminals. A vacuum tube diode, now rarely used except in some high-power technologies and by enthusiasts, is a vacuum tube with two electrodes, a plate (anode) and cathode. The most common function of a diode is to allow an electric current to pass in one direction while blocking current in the opposite direction Thus, the diode can be viewed as an electronic version of a check valve. This unidirectional behavior is called rectification, and is used to convert alternating current to direct current, including extraction of modulation from radio,the source from http://www.top-beauty-salons.com/index.php/category/products/diode-laser-products/
Beautymachine, let us gain at least a basic understanding of how LED's work. Apparently you Googled the wrong term. I suggest that we begin with a clear understanding of atomic structure, particularly concentrating on Si, Ga, Ge, As, Se, and P.
Next let us work to correct your understanding of energy transfer and the characteristics of photons, positrons, and electrons.
It is not particularly difficult to gain a basic understanding of this subject matter, although work in detail and in-fine may be severely demanding unless you have a correct understanding of the basics.
Rocmike you do know how to google and copy and paste but you do not have the intelligence to understand or apply it.
