Picosecond time‐resolved laser spectrometer with expanded delay range

Picosecond time‐resolved laser spectrometer with expanded delay range

We have developed a pump‐probe picosecond spectrometer capable of time‐resolved studies spanning nine decades in time, from the picosecond to the millisecond regimes. The system operates at repetition rates up to 2 kHz with ∼40‐ps time resolution. Pump and probe beam average powers are ∼10 mW. The s...

Zusammenfassung:We have developed a pump‐probe picosecond spectrometer capable of time‐resolved studies spanning nine decades in time, from the picosecond to the millisecond regimes. The system operates at repetition rates up to 2 kHz with ∼40‐ps time resolution. Pump and probe beam average powers are ∼10 mW. The system is capable of studies of molecular dynamics in complex systems such as proteins, where internal motions span a wide range of time scales.
