Green laser is a device capable of absorbing a specific frequency of a beam rather than releasing a beam of light

Green laser is located in the material cavity, when the working substance of a level between population inversion occurs when the distribution frequency in the level of spontaneous emission spectrum line width in laser pens, will gain and expand; because there are all kinds of cavity loss, blue laser pointer, in which the transmission can continue to decay. Oscillation, depends on the gain and loss of the burning laser pointer.laser pens1

Green laser to get the light to make the light in the self oscillating cavity round trip by gain, at least in the propagation of.Laser pens loss compensation is generally used in semiconductor material such as “gain medium” produce a focused beam, which is a blue laser pointer is a coherent beam vibration direction, the vibration frequency of the same, the same phase or the phase difference of two beams remain constant, burning laser pointer interference phenomenon in the region will be met.laser pens2

The opposite of green laser, is a kind of anti laser beam equipment can absorb specific frequencies rather than release beam. The incident beam into laser pens can interfere with each other, finally will offset each other. In this process, the blue laser pointer can be converted into heat energy released. And this process generally requires loss media participation with the laser gain medium loss medium such as silicon can make this.Burning laser pointer loss media is relative.
