  1. The laser power is detected through the pd ’ s movement across the faculous region. when the value of the peak value of laser power is got, the power of the facular boundary points can be found according to definition of the facular boundary such as “ 1 / e ~ 2 ” theory. then the equation of the facular boundary can be made fitting by using the least square method, and calculate the beam divergence at last

    採用兩個光電探測器分別檢測光束不同高度上的兩個光斑,在確定光斑中心最大光強值后,根據光斑截面尺寸的1 / e2定義,得到光斑截面邊界點的光強值,並以其為標準判定光斑截面的邊界點,對探測到的邊界點通過最小二乘法進行擬合,得到橢圓光斑截面的方程,根據空間幾何關系求出發散角。
