J. Bourderionnet et al., Spatial mode control of a diode-pumped Nd : YAG laser by use of an intracavity holographic phase plate, OPTICS LETT, 25(21), 2000, pp. 1579-1581
We present a new method of realizing phase plates by phase-volume holograph
y on a photopolymer film. We implement such a component in a diode-pumped N
d:YAG oscillator to control the output spatial beam profile. Flattop super-
Gaussian and square-shaped beams are obtained. (C) 2000 Optical Society of
