Product Description

Nd:CE:YAG

Nd:Ce:YAG is an excellent laser material used for no-water cooling and miniature laser systems. the (Nd,Ce): YAG laser rod weproduce has the characteristics of high efficiency( laser efficiency than Nd: YAG high about 30-50%), low threshold, anti-violetradiation and high repetition frequency for lasers operation. It has achieved the international advanced level .it is the mostideal laser material for the high repetition air cooling lasers. It suitable for different modes of operation (cw, pulsed ,Q-switched, mode locked, doubling of frequency ) and high-average power lasers.

Q-switching

Q-switching is achieved by putting some type of variable attenuator inside the laser's optical resonator. When the attenuator is functioning, light which leaves the gain medium does not return, and lasing cannot begin. This attenuation inside the cavity corresponds to a decrease in the Q factor or quality factor of the optical resonator. A high Q factor corresponds to low resonator losses per roundtrip, and vice versa. The variable attenuator is commonly called a "Q-switch", when used for this purpose.Initially the laser medium is pumped while the Q-switch is set to prevent feedback of light into the gain medium (producing an optical resonator with low Q). This produces a population inversion, but laser operation cannot yet occur since there is no feedback from the resonator. Since the rate of stimulated emission is dependent on the amount of light entering the medium, the amount of energy stored in the gain medium increases as the medium is pumped. Due to losses from spontaneous emission and other processes, after a certain time the stored energy will reach some maximum level; the medium is said to be gain saturated. At this point, the Q-switch device is quickly changed from low to high Q, allowing feedback and the process of optical amplification by stimulated emission to begin. Because of the large amount of energy already stored in the gain medium, the intensity of light in the laser resonator builds up very quickly; this also causes the energy stored in the medium to be depleted almost as quickly. The net result is a short pulse of light output from the laser, known as a giant pulse, which may have a very high peak intensity.
