Influencing parameters in time resolved picosecond spectroscopy and a new light gate method Academic Article uri icon


  • We show that the open period of a CS2 light gate, triggered by a picosecond optical pulse, depends on the optical pathlength through the CS2. An alternative to the light gate is suggested for time resolved spectroscopy. The working principle is based on scattering induced in CS2. We have found that the broadband emission from H2O or D2O excited by a 5300 picosecond pulse is also of picosecond duration, but the blue part is delayed with respect to the red. From this delay time the lifetime of the ground state vibrational levels may be measured directly. 1973.
