Mid-infrared ultra-short pulse frequency comb generation setup
Abstract
Mid-infrared (MIR) spectroscopy provides not only a powerful tool for understanding thestructure of molecule, but also for performing non-intrusive diagnostics of composite materialsin the gas, liquid or solid phase. MIR frequency-comb-based spectroscopy has shown greatpotential to address the great challenges in realizing high speed, sensitive precision MIRspectroscopy over broad spectral ranges. However, current development of MIR frequencycomb-based technologies is still hindered by the lack of broadband frequency comb sources. Wehave been exploring new techniques for broadband frequency comb generation. It can beapplicable for the whole mid-infrared wavelength range, i.e. 3-24 ?m. The objective of thisDURIP proposal is to develop a prototype instrument for laser frequency comb generationin the wavelength (6-12 ?m), based on the techniques we have developed. Once successfullyimplemented, this instrument can be used for the following research and technologydevelopments:1) Generate sub-picosecond laser pulses with potential application in ultra-fast MIRspectroscopy and study of light matter interaction in fs-ps time regime at MIRwavelength.2) Generate laser frequency combs at any wavelength from 6-12 ?m, filling thetechnological gap in MIR laser frequency comb generation beyond 6 ?m.3) Realize dual frequency comb generator and apply it for high speed high precision MIRspectroscopy.
