We describe an optical pulse-compression technique that uses a pair of Brewster-angled TeO2 crystal prisms. The negative group-velocity dispersion of the TeO2 prisms is much larger than that of fused quartz or other dense flint glasses. This permits the distance between the prisms to be shortened considerably, approaching that of a grating (1200 lines/mm) pair. The transmission for 633-nm monochromatic light through the prism is 99.8%, and the total transmission through the prism pair is higher than 90%. Optical pulses of 800-fsec duration from a synchronously pumped cw dye laser have been successfully compressed to 120 fsec.
