Paper Abstract

We report on a thulium doped silica fiber ASE source for absorption spectroscopy of CO2. The average spectral power of this source was 2.3-6.1 μW/nm. This low spectral power of this source posed limitation in the sensitivity of the system which was overcome by using an ultrashort pulsed Raman amplifier system with 50-125 μW/nm average spectral power. This system produced CO2 sensitivity better than 300 ppm making measurement of CO2 possible at standard atmospheric concentrations.
