AI Article Synopsis
- A new femtosecond optical parametric oscillator (OPO) has been developed using orientation-patterned gallium phosphide (OP-GaP) as the gain material.
- This system can generate high-repetition-rate femtosecond pulses in the 5-12 μm wavelength range with average power levels from a few milliwatts to tens of milliwatts.
- The OPO is the first to operate across the molecular fingerprint region and has been successfully used for broadband Fourier-transform spectroscopy with water vapor and polystyrene.
Article Abstract
We report a femtosecond optical parametric oscillator (OPO) based on the new semiconductor gain material orientation-patterned gallium phosphide (OP-GaP), which enables the production of high-repetition-rate femtosecond pulses spanning 5-12 μm with average powers in the few to tens of milliwatts range. This is the first example of a broadband OPO operating across the molecular fingerprint region, and we demonstrate its potential by conducting broadband Fourier-transform spectroscopy using water vapor and a polystyrene reference standard.

The mid-infrared spectral region opens up new possibilities for applications such as molecular spectroscopy with high spatial and frequency resolution. For example, the mid-infrared light provided by synchrotron sources has helped for early diagnosis of several pathologies. However, alternative light sources at the table-top scale would enable better access to these state-of-the-art characterizations, eventually speeding up research in biology and medicine.

Few-cycle pump pulses (≲15, 100 pJ) from a near-infrared electro-optic frequency comb are provided via nonlinear soliton-like compression in photonic-chip silicon-nitride waveguides. Subsequent intra-pulse DFG in periodically poled lithium niobate waveguides yields MIR frequency combs in the 3.
