Paper Abstract

We report on the measurement of the output beam phase distribution of the high power, 30 cm aperture, Nd:glass laser HELEN using a self referencing cyclic radial shear interferometer. This near field interferometry technique for beam quality measurement is evaluated by comparison with measurements of the far-field intensity distribution. Results are also presented on the evolution of the thermal gradients and their effects on the transmitted wavefront quality through the final disc amplifiers following a laser shot.
