A beam of pulsed laser radiation at the wavelength ฮป = 0.532 ฮผm was diffracted at a circular diaphragm to produce a hollow-shape intensity distribution in the near field. This light distribution was used to pump an Nd:YAG laser, resulting in the formation of an inversion profile with a minimum at th
