Abstract

Laser collimation is required in many experiments based on lasers. Some laser experiments demand a high quality of collimation, e.g., the optical coherent processor, image transformer, and Fourier transform generator. A device is required to test the collimation of lasers in such experiments. We have suggested a modification in existing collimation testing techniques by which sensitivity can be improved. Theoretical analysis and experimental results demonstrate twice the improvement in sensitivity when used with previous techniques.
