data, the movement will be reduced with the increase of input energy. That, dynamic laser pulses in the high energy input (Q modulation pulse) is the peak power is increased, but the pulse energy

decreases. Passive saturable absorber Q-principle: the passively Q is the use of of passively crystal saturable absorber. Material becomes transparent as the energy density increases up. The energy

density reaches a certain high-value, the material will be "saturated" or "bleaching", which leads to produce a high transmission rate. The operation mode of green laser pointer is very simple.
The specific parameters and performance of green laser pointer has been described
Can saturable absorber in the bleaching process is based on the saturation of the spectral transition. If the laser wavelength will be a high absorption rate of the materials installed in the laser

cavity, it will prevent laser oscillation at the beginning. As the gain increases in the pump pulse duration and more than round-trip loss, the cavity of the luminous flux will increase sharply,

resulting in passive Q-switch is saturated. Under these conditions, the loss is at the end in order to establish the Q-switched pulse. Turn the power off, remove the electro-optic crystal (Note Do

The course of their work. The working principle and structure of the laser. We usually light-emitting objects is called the light source, such as solar, electric lights, burning candles and so on. Light has energy, it can make the object hot, so that the photographic film photosensitive energy conversion phenomenon. Light containing the beam, the beam launched into people's eyes, was caused by human vision, so we can see the light emission of the light. So why do we also see non-luminous objects? Because the light emission of the light shines on them, non-luminous objects by light, the diffuse reflection of light in all directions into the goal of our eyes so we can also see non-luminous objects. The power of green laser pointer by the way is 200mW.
