Abstract : This report summarizes our research during the past year on the interaction of short pulses of infrared radiation produced by a CO2-TEA laser with the cornea. The report discusses the re-establishment of our laboratory, revision and testing of our computer program for computing temperature histories, confirmation of earlier results for single-pulse damage thresholds, the determination of the damage threshold for a sequence of two 80 ns pulses at 5 Hz, and correcting problems with the laser in order to achieve uniform pulse amplitudes at higher pulse repetition frequencies.
