Paper Abstract

We have created a program for the modeling of laser beams to answer systems questions. We have used the IMAGE program for wavefront modeling and far field modeling. In order to answer such questions as 'How much astigmatism is permitted in a Gaussian beam clipped at one-half the one-over-e-squared-radius with an obscuration ratio of 0.3 if 75% of the energy is to lie within 2*lambda*F#?' one might need to use a large lens design program. We have developed the IMAGE program so that the systems engineer has a good tool to answer such questions quickly. In fact, we use a large optical design program for our lens design work and still find that IMAGE is much more convenient and quicker than the more powerful program.
