Description
Spectral diagnostics of infrared and THz free electron lasers typically rely on either laser-based techniques or large benchtop FTIR systems, making alignment and beamline integration time-consuming. We present AURA, the most compact broadband FTIR spectrometer developed by WAIV FTIR GmbH, covering a continuous spectral range from 3 to 600 µm (100 THz to 0.5 THz). The instrument fits in a 130 × 150 × 80 mm housing and reaches a resolution down to 1 cm⁻¹, operating with both pulsed and CW sources.
AURA uses fully reflective optics together with broadband detection, therefore no beamsplitter exchange is required during measurement and beamsplitter absorption features contribute to the measured spectrum. Data acquisition and analysis are handled through a browser-based interface that requires no dedicated installation.
The poster will present the instrument concept, measurement results from various FELs and laser laboratories, and use cases for spectral diagnostics at IR-FEL beamlines. WAIV FTIR GmbH is a spin-off of the THz beamline at FLASH, DESY (Hamburg).
