Beam Diameter, Divergence Measurement—Laser Profile Analyzer

 
      Laser profile analyzer is adopted to test laser transverse mode energy distribution. One-dimensional, two-dimensional and three dimensional energy distribution will be shown on the software, as well as laser transverse mode characteristics of spot diameter, divergence, ellipticity and etc.
      The software can provide four calculating method testing results of laser spot diameter, one of the most widely used definition method is 13.5% of peak value as the boundary (1/e2), and the beam ellipticity definition is the ratio of 4 Sigma spot diameter on minimum direction and 4 Sigma spot diameter on maximum direction.
      Laser divergence is a physical parameter to describe laser divergence degree, the testing method is roughly summed up as testing beam spot diameter both on near field and far field, by calculating the distance between the two spot diameter deviation of the two position of tangent value, which can determine the divergence angle value, then converted into space angle value.
