abstract = {Mid-infrared laser diodes are highly attractive sources for gas
spectroscopy applications due to the presence of strong
absorption lines of many gaseous species in this spectral range.
Particularly, the 2.3 – 3.3 µm wavelength range contains strong
absorption lines of some pollutants as CH4, NH3 or HF while CO2
and H2O interference absorption lines are very low which renders
possible the highly selective and sensitive detection of these
pollutants. Vertical-cavity surface-emitting lasers (VCSELs)
appear especially well adapted to be used as laser sources for
absorption spectroscopy due to several intrinsic characteristics
that they offer. The low threshold, single-mode operation, the
circular output beam with low divergence are only some of their
well-known advantages.
