Abstract

In the long-distance and high-precision Laser 3D imaging system, the response efficiency of the imaging detector in the near-infrared band is much less than that in the visible band, so the system requires higher output power of the 1064nm laser source, the laser is required to have high efficiency, small volume, good beam quality, high peak power and other output characteristics. In this paper, a complementary absorption technique of Nd:YAG / Nd:YVO4 twin-crystal laser is presented, in which the wide-spectrum absorption characteristics of Nd:YVO4 laser crystal are complementary to the good thermophysical properties of Nd:YAG Laser Crystal, greatly enhance the laser output characteristics.
