| Abstract: | Measurements on an optical discrimination amplifier are presented which demonstrate its ability to increase the S/N ratio of single ultrashort pulses by 2 to 3 orders of magnitude. The amplifier consists of a series of amplifiers and dye cells such that for each dye-amplifier section the small-signal gain is less than one. |
