    How to use the Gaussian Beam Width Calculator<\/h3>\n
      \n
    1. Select SuperGaus,<\/strong><\/em> and input 1<\/strong><\/em> in LargeNum X.<\/strong><\/em> This means source is Gaussian.<\/li>\n
    2. Click Gaussian Beam Width Calculator,<\/strong><\/em> then the following is shown.\"image003\"
      \nFig. 2.<\/li>\n
    3. Sigma is value of HW 1\/e for Gaussian Amplitude. Input proper value.<\/li>\n
    4. Rim Radius is the half of source width. Input proper value.<\/li>\n
    5. Click Calc, and repeat above procedure changing sigma until FW 1\/e^2 of Amplitude Squared is same as Rim diameter(source width).
