RF noise induced laser perturbation for improving the performance of non-resonant cavity enhanced absorption spectroscopy.
We present a novel strategy for suppressing mode structure which often degrades off-axis cavity enhanced absorption spectra. This strategy relies on promoting small, random fluctuations in the optical frequency by perturbing the injection current of the diode laser source with radio frequency (RF) b...
