[ALPSp1-33] Dual comb spectroscopy measurement using all-polarization maintainingsingle-cavity SWNT mode-locked dual-comb fiber laser

*YIFEI ZHU¹, Shotaro Kitajima¹, Norihiko Nishizawa¹ (1. Nagoya University)

HCN gas absorption spectroscopy using all-PM single-cavity dual comb fiber laser was demonstrated. With 25-fold averaging, a high signal-to-noise ratio was achieved, enhancing the precision of the spectral data.
