Irradiated with laser light mirror, the mirror will be laser reflection out?

There are no mirror reflectivity, the mirror is generally about 90%, optical instrument can reach about 97%; the rest is then is absorbed; we assumed that a laser pointer 1000mw effective radiated power, the active area to 1 mm2, with up to 97% if the specular reflectance of the reflected beam of light to, then there is a 30W energy is absorbed into the heat, you can imagine, the role of 30W of power in 1 mm2, only micron thickness reflective surface, even if it is used as a reflective silver material has been vaporized, laser will be blocked after penetrating look at the mirror.

Or laser pointer 2000mw active area of ??1 mm2, up to 97% if the specular reflection rate to the reflected beam of light, then there is 60W energy is absorbed into heat. Conversely, if the power is small, or the effect of a larger area of ??the reflecting mirror or by other methods have higher thermal conductivity, the reflection effect can be sustained.

That is, the mirror is the first to be burned, or the light reflected off now? If the gun perpendicular to the laser mirror radiation, laser gun will be damaged it?

Mirrors have damage threshold, there is a possibility of being broken. For example, laser pointer 200mw using high damage threshold of the mirror, the laser can be reflected off. The light reflected back to the laser, then the mirror as the equivalent of a mirror, the laser resonator has changed. Lasers can add some inside isolator for preventing reflected laser damage crystals.

By adjusting the length of laser pointer the different ways of adjusting the first mirror. It is in the right hand side of the photo, so the mobile frame for the same number of the pictures on the left (the back of the body) or at the center. Please adjust the center of the inner hole of the inner sleeve of the laser light path to the mirror. If the level of the center, adjust the frame angle. Just a slight angle will make a big move. So, it slowly adjust. Please adjust as the center. The original position of the laser on the use of the software. When the second mirror is too far away, it may be too far from the center, so give it a go near distance once again in the middle area of the Y axis side. Right Y axis before irradiation treatment area. Back to the original position, if it is too far from the middle of the frame, the adjusted angle. A little time to fix the angle of the screw in the mirror. Move the Y axis to adjust it, so there is no slip before the process domain of the different ways and the original point of the position. At the same time, by adjusting the vertical axis sliding adjusted the mirror base for adjusting screw, even if it is moving in the horizontal direction, you can also adjust the level of the horizontal direction angle adjustment, if it is so, the first reflector including aluminum frame to move together, aluminum frame parallel.
