Abstract
The time resolution of a heterodyne-detected accumulated photon echo has been improved significantly by using a dye laser whose lasing frequency is repetitively scanned. A time resolution of less than 30 fsec was obtained, even with a non-mode-locked cw dye laser. This technique is applicable provided that the absorption recovery time of the sample is longer than the repetition period of the frequency-scanning dye laser. The absorption recovery times of several dyes that were doped with polyvinyl alcohol have also been measured.
