title: Spatial mode control of a diode-pumped Nd:YAG laser by use of an intracavity holographic phase plate.
abstract: We present a new method of realizing phase plates by phase-volume holography on a photopolymer film. We implement such a component in a diode-pumped Nd:YAG oscillator to control the output spatial beam profile. Flattop super-Gaussian and square-shaped beams are obtained.
