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 350 – 1600 nm range, while a monochromatic probe can be used up to 24 μm. The probe delay stage is configurable from up 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.
- Higher repetition rates available; contact sales@lighton.com for details.
- Without external spectrograph.
- External sample placement option is available.
