Abstract

We discuss a continuous-wave (CW) multi-wavelength fibre laser operating in the L-band, which has applications to gas sensing. Multi-wavelength operation of between two to eight lasing peaks with a spacing of around 0.9nm between each peak was demonstrated by placing silicon wafers in a micro-optic cell in order to produce a Fabry-Perot effect. Tuning over a region of 1565 to 1595nm was done by adjustment of the attenuation within the laser cavity. For our system we are interested in wavelength tuning for the detection of gases such as Hydrogen Sulphide (H2S) and Carbon Dioxide (CO2).
