  1. Abstract : the far - field spot characteristics of laser converted by random phase plate are analyzed theoretically, including the shape, size, rotational symmetry and diffractive efficiency of the spots, as well as the distribution of subsidiary spot. by comparing the influence of phase element shape ( triangular, square and hexagonal ) on the characteristics, we found that the random phase plate with hexagonal array structure is more suitable for the beam smoothing in laser fusion

    文摘:從理論上分析了激光經隨機位相板變換后在遠場的光斑特性(包括光斑的形、大小、旋轉對稱性、衍射效率以及旁瓣分佈) ,通過比較三種形位相元(等邊三角形、正方形和正六邊形)的遠場光斑特性,得知正六邊形位相元的隨機位相板更適合於激光變中的勻化。
  2. According to the guidline, two nd : yag lasers have been designed and set up, one is end - pumped by lower output power ld using a selfoc micro lens, and the other is end - pumped by high output power ld using a pair of lenses are designed, and the characteristics such as output power and power stabilization of both solid - state lasers are investigated. thirdly, when an empty liquid crystal cell is inserted in the cavity of the nd : yag laser pumped by high power ld, the laser can operates in single axial mode. finally, according to the relationship between the laser output power and the longnitudinal a ld - end - pumped nd : yag laser sensor for displacement measurement has been investigated theoretically and demonstrated experimently, the results indicate that when the mean radius of pumping inside the laser cavity is far less than that of the oscilating laser mode, the exponential of the output power is a gauss function of the longitudinal positon of focused spot of ld pumping beam, both the measurement range and the sensitivity are dependent on the incident pumping power, as the incident pumping power is increased, the measurement range is enlarged and the sensitivity is improve d
