Continuous scanning from picoseconds to microseconds in time resolved linear and nonlinear spectroscopy

We describe a setup of two synchronized femtosecond 1  kHz oscillator/regenerative amplifier laser systems that allows to continuously delay the amplified pulses up to 50 μ s , with a jitter of ⩽2  ps . It can be realized by facile modification and combination of equipment that already exists in man...

Description
Summary:We describe a setup of two synchronized femtosecond 1  kHz oscillator/regenerative amplifier laser systems that allows to continuously delay the amplified pulses up to 50 μ s , with a jitter of ⩽2  ps . It can be realized by facile modification and combination of equipment that already exists in many femtosecond laser laboratories. It opens up a variety of experimental possibilities, particularly for the investigation of systems that display dynamics over a wide range of time scales, such as peptides and proteins. As an example we discuss the application of this setup for time resolved IR spectroscopy.
