| description | An optical detector based on piezoelectric detection of the photo acoustic effect
in an absorbing metal plate is reported. Such a detector has been used in an
experiment for measuring a Gaussian laser beam diameter using the knife-edge
method. The responsivity of the detector varied from 4.05J.LV/mW at 68Hz to
1.25J.LV/mW at 211Hz. The Gaussian laser beam diameter obtained from the
experimental data is (0.88 ± 0.02)mm and this value is comparable with the
value stated in the laser specification note. |
