Apparatus for real-time control of beam profile of laser unit
摘要
The apparatus for real-time control of the beam profile of a laser unit (2) comprises an optical correlator (8) which is located in the laser beam path. The correlator compares the actual beam profile with a specified profile and produces a significant output signal only if these two profiles coincide.
