  • Tuning System for a Tuneable Diode Laser Spectroscopy Device comprising a Thermo Electric Cooler and a further Cooler
    Publication number: 20150280399
    Abstract: The present invention relates to a laser thermal tuning system for a tuneable diode laser spectroscopy device, the system comprising: a thermoelectric cooler; a further cooler; a laser diode arranged between the thermoelectric cooler and the further cooler and coupled to each of the thermoelectric cooler and the further cooler; and control means for controlling each of the thermoelectric cooler and the further cooler to control the temperature of the laser diode and thereby vary the output wavelength of the laser diode. This arrangement provides the benefit of a TDLAS analyser with an analytical wavelength range which is sufficient to analyse a large number of species yet which is low cost and has a long operating life.
