Infrared spectroscopy is a non-destructive, non-contact measurement technique that can acquire information on molecular structures. Time-stretch infrared spectroscopy (TSIR) has been developed as a fast infrared spectroscopy method, but a large and not robust optical parametric oscillator has been used as an infrared light source. In this study, we developed a compact and robust TSIR system in which pulsed light in the telecommunication wavelength band output from an Er-doped fiber laser is chirped by an optical fiber, wavelength-converted to infrared light, and irradiated onto a sample.
