Abstract:

The Studies in Optics described are directed towards the assessment and improvement of laser output characteristics and to problems in the use of the coherent output of a laser in optical systems. Section 2 consists of a study of techniques for assessing and improving laser beam propagation characteristics including apodization of coherent imaging systems and holographic methods of measuring the amplitude and phase of pulsed laser beams. The design of efficient solid state lasers is addressed in Section 3 with particular reference to methods of enlarging the TEMoo mode size and the correction of thermally induced optical distortion in repetitively pumped ruby laser rods. Section f is a study of laser beam steering techniques leading to devices in the multi-MHz range using a new large bore argon-ion laser design with intra-cavity modulation. The final portion Section 5 is concerned with procedures for overall lens evaluation using optical transfer function data exemplified by the specific data on a 3 inch f4.5 wide angle lens.
