Abstract:
Tuneable Diode Laser Absorption Spectroscopy (TDLAS) technology for gas sensing
has had reliance on, and has benefited from, devices developed for the optical
communications sector, namely distributed feedback laser diodes. The range in
wavelengths of available DFB lasers coincides with absorption spectra of many gases
of environmental and industrial interest. However, since the distributed feedback laser
diode has a narrow wavelength tuning range, only one gas can be targeted without
changing the laser. The objective of this thesis is to advance the strategic capability
required to allow development of TDLAS multi-species gas detection systems using
widely tuneable laser diodes recently developed for the telecommunication sector.
In this thesis, the application of widely tuneable laser diodes and a single frequency
tuneable laser diode to trace gas detection in the near infrared region of the spectrum
is reported.
