Abstract

Optical systems which transmit power density optical radiation present real design and implementation challenges. Sophisticated multi-disciplinary methods have been developed to support the design and analysis of the interaction of the optical radiation field and the transmissive and reflective optics which the field interacts with. The primary effect which results are distributed thermal deformation of the optical surfaces resulting in undesirable aberrations, loss of Strehl and beam 'quality'. Modern optical systems involve the use of adaptive optical systems which mitigate the effect of these aberrations within their spatial and temporal correction bandwidths. The authors have been involved in a study, which addresses the closed loop correction of thermally induced beam train aberrations using computational numerical models to describe the wavefront effects. This paper reports on the analysis methods used and describes some preliminary results.
