Abstract :
A frequency-swept source for broadband mid-infrared spectroscopy is reported. A mid-IR laser source capable of rapidly tuning over up to 900cm-1 within a total accessible range of 2304-3752cm-1. The rapid tuning range is believed to be the widest reported for an OPO of this type, while the tuning rate and resolution are sufficient for real time IR spectroscopy of solid and liquid samples in techniques requiring high-brightness and wide spectral coverage. The performance and limitations of the OPO system will be discussed and further spectroscopic examples presented.
