Phase-Stabilized 1-GHz Fiber-Laser Frequency Combs at 2~5um for Coherent Fourier Transform Spectroscopy
The GHz-rate phase-stabilized fiber-laser frequency comb system is proposed to be used as a light source for coherent Fourier transform spectroscopy. The system will be developed based on our proprietary glass/fiber technology, which features a low-cost, robust, highly stable, mid-infrared light source that enables the development of a robust portable c-FTIR spectrometer for absorption measurements of many important chemical/biological species. Both the pulse repetition rate and carrier-to-envelop offset frequency of the comb system are stabilized. Important key concepts in the proposed system have been demonstrated in the Phase I effort. This Phase II program will focus on the development of a prototype device, which will be delivered to NIST at the end of the Phase II program for use in proof of principle experiments demonstrating the utility of the device for high-resolution, coherent spectroscopy.
