Abstract

We present a Tm:fiber based broadband ASE source which was used for atmospheric CO2 detection. The average spectral power of this source was limited to ∼6.1 μW/nm which was the main limitation in detection of trace concentrations of gases. This shortcoming was overcome by using an ultrashort pulsed Raman amplifier system with maximum of ∼127 μW/nm of spectral power density which was able to provide sensitivity better than 300 ppm for CO2. In addition, improving the average power of the ASE provided an essential tool in lab to characterize optical elements with sharp spectral features around 2 μm. © 2011 SPIE.
