Laser system used for time-resolved transient absorption in visible and near-IR regions. CCD detctor syncronised to measure two full spectra per duty cycle (i.e. 2x1 kHz).
Widely used laser-system for picosecond fluorescence decays. Two detection systems: (1) Time-correlated single photon couting with micro channel plate photomultipliers giving time resolution down to about 25 ps and (2) streak camera system for array detection and time-resolution down to about 1 ps. Pulse-picker for slower rep. rate is availble.
Nanosecond flash photolysis
Laser type: YAG + OPO (410-750 nm) Parameter summary: 10 Hz, 7 ns, 160 mJ @355 more at 1064 and 532 nm, 266 nm also availble
Transient absorption and emission on > 10 ns time-scales. Three detection systems availble: (1) gated ICCD camera, (2) monochromator/photomultiplier and (3) balanced photo diodes (high sensitivity slower resonse)
