Optimized Wavelength-tuned Nonlinear Frequency Conversion
Project Description
Efficient nonlinear optical conversion requires a precise phase-matching condition. Due to optical dispersion (light having a different index of refraction for different wavelengths), the phase-matching condition is only maintained over a narrow wavelength band. Generally temperature- or angle-tuning of the nonlinear crystal is required to maintain phase-matching during wavelength-tuning. We will explore a novel technique to tune the phase-matching condition and thus extend the range over which light can be efficiently converted.
More »Anticipated Benefits
There are numerous spectroscopic applications both in and out of NASA that require wavelength-tunable laser sources. These include differential optical absorption spectroscopy instruments for methane, carbon dioxide, water vapor, oxygen, etc. and various in-situ spectrometers.
