The HARPIA-TA ultrafast transient absorption spectrometer provides pump-probe measurement functionality in a HARPIA system. Several probe light configurations and detection options are available: from a photodiode for single‑wavelength detection to white-light supercontinuum probing combined with spectrally-resolved broadband detection. HARPIA-TA features extensive automation options providing pump and probe beam position tracking and alignment, pump polarization control, supercontinuum generator switching, sample positioning, as well as switching between transient absorption and transient reflection measurements. Broadband probe options cover a 330 – 1600 nm range, while a monochromatic probe can be used up to 24 μm. The probe delay stage is configurable from 2 ns to 8 ns.
HARPIA-TA features market-leading sensitivity of 0.05 mOD (10-4 ΔT/T) and can be operated at high repetition rates of up to 1 MHz when used with a PHAROS or CARBIDE laser and an ORPHEUS series OPA, which allows the study of transient absorption dynamics with excitation pulse energies down to several nanojoules.
HARPIA-TA is compatible with cryostats and peristaltic pumps, and the capabilities of the spectrometer are extendable using expansion modules.
- A wavelength-tunable source such as ORPHEUS-HP is used instead of a laser-excited white-light continuum.
- An extended tuning range of ORPHEUS‑HP; see specification for more details. Also applicable to UV / VIS / NIR / SWIR configuration.
- Up to 24 μm available upon request; contact sales@lighton.com for more details.
- Estimated as the standard deviation of a set of 2500 spectra measured in SCHOTT OG530 glass with 54 nJ, 370 nm pump and > 4.5 mOD at a maximum of the spectrum. Not applicable to all samples and configurations.
- Estimated as the standard deviation of a set of 2000 spectra measured in SCHOTT OG530 glass with 515 nm pump and > 10 mOD at a maximum of the spectrum. Not applicable to all samples and configurations.
- Without external spectrograph.
- External sample placement option is available.
