Abstract: | 0 –S1–Sm–Sn multilevel system. An Sm→S1 absorption recovery time of τS1 A=(600±100) fs is determined. The picosecond and femtosecond pulse excitation leads to S0→S1 ground-state absorption bleaching and S1→Sm first excited-state absorption bleaching. The excited-state absorption cross-sections σS1 ex(S1→Sm) and σSm ex(Sm→Sn) are determined. Received: 3 June 1996 |
