PURPOSE:To take an accurate measurement by varying the output of the laser and drawing the graph between the laser output and a burn pattern, and reducing the gradient of the obtained graph to 1/2 and finding the radius of the laser beam. CONSTITUTION:While an irradiation time is made constant, the laser output is varied to find an acryl burn pattern radius ra. The gradient of the straight line obtained when the lateral axis is set to the logarithm of the laser output, the radius of the laser beam is denoted as r0, and the longitudinal axis is set to (ra/r0)<2> is reduce to (1/2) and the radius r0 of the laser beam is found. |
