Chauhan, Pamela Bowlan,Jacob Cohen, Rick Trebino; Georgia Tech, USA. Weintroduce single-grating and single-grism pulsecompressors, which are compact and automaticallyaligned for distortion-free output, and the latterof which compensates for significant materialdispersion up to third order.CMMM7 • 5:15 p.m.Label-Free Optical Detection of BiomolecularReaction Kinetics in Microarray Format forHigh-throughput Screening Applications,Yung-Shin Sun 1 , James P.
