Light Conversion's HARPIA-TG is a transient grating spectrometer for carrier diffusion coefficient and lifetime measurements.
It operates as a non-invasive and non-destructive pump-probe spectrometer exciting the sample with laser interference and, subsequently, recording the transient grating – spatial refractive index modulation. A delayed beam probes the modulation decay, which corresponds to the carrier diffusion. By automated change of the grating period, the technique provides a detailed information on the dynamics of carrier propagation.
Coupled with CARBIDE or PHAROS laser with integrated optical parametric amplifier (I-OPA), the compact system is fully automated and computer-controlled via advanced measurement and analysis software. Thus, the user only needs to put the sample in the holder and start the measurement to obtain the diffusion coefficient in a matter of minutes.
Features:
- Carrier diffusion coefficient in a matter of minutes
- Non-invasive measurement technique
- Fully automated and computer controlled
- Continuous setting of grating period
- Sensitivity down to µJ/cm² excitation level
- Advanced measurement and analysis software
- Photoluminescence (PL) measurement option
