Description
Full text: We measured the thermal distortion induced on an optical probe beam passing through a diode end pumped Nd YVO4 laser crystal under lasing and non lasing conditions A Hartmann wavefront analyser was used to measure the probe beam wavefront which was analysed with a Zernike polynomial basis. The resulting thermal distortions were compared with a model of thermal lensing. For high pump powers good agreement was found. Some limitations in the use of the Hartmann analyser were identified. Our ultimate goal is to use a deformable mirror to compensate in real time for the beam distortions. Copyright (2005) Australian Institute of Physics
