Abstract

Simple low-cost modulators based on the Raman-Nath regime of acoustooptic diffraction have been demonstrated. Experimental results on internal laser modulators constructed from some dense flint glasses and fused quartz are presented. 100% modulation of He–Ne lasers with rise times on the order of 1 μsec are obtained with 10-MHz modulator drive powers of 100 mW. The theory necessary for the design of this class of modulators is reviewed and compared with the experiments.
