Femtosecond Transient Absorption Pump-Probe Spectrometer
  • Turnkey transient absorption pump-probe femtosecond spectroscopy system
  • Multichannel and single-channel detection of photoinduced optical density changes (DOD).
  • Detection of transient absorption in solutions, thin films and solid samples
  • < 100 fs temporal resolution
  • Probe and reference channels
  • Computer controlled imaging spectrometer with four-grating turret
  • NMOS linear image sensors with high signal-to-noise ratio
  • Internal all reflective white light continuum generator
  • Internal second harmonic generator for the sample excitation
  • Optional CDP 2017 optical parametric amplifier for single-channel probe
  • ExciPro 2.5 software for data acquisition, transient spectra analysis and chirp compensation

ExciPro is the first on the market professional system for time-resolved ultrafast transient absorption pump-probe spectroscopy. Two linear image sensors are placed in the focal plane of an imaging spectrometer to measure probe and reference spectra, and the reference channel is used in transient absorption or photometric measurements to get best signal-to-noise ratio.

CDP Systems Corp. has been manufacturing femtosecond pump-probe spectrometers since 2000, and we satisfy customer’s requirements introducing a wide range of ExciPro configurations and options.


  • Multichannel visible probe spectral range: 350 nm - 1000 nm
  • Multichannel infrared probe spectral range: 900 nm - 1600 nm
  • Single-channel probe spectral range: 250 nm - 2500 nm
  • Maximum delay between probe and excitation pulses: 2.0 ns (4.0 ns in the optional double-pass configuration)
  • Minimum step of the optical delay line: 1.56 fs
  • Maximum pulse repetition rate at multichannel detection: 1 kHz
