Accurate measurements of the SO(2) absorption cross section between 290 and 317 nm have been made using a frequency-doubled dye-laser source with a 0.05-nm linewidth. The spectrum is applicable to the differential absorption method of detecting SO(2)

A process for making Buried Heterostructure (BH) lasers was established. Using PbSnSe as active material long wavelength BH-cw-emission at 80 K down to 1026 cm-1 was reached. For shorter wavelengths we employed PbSrSe and obtained BH-cw-emission up t

The use of differential lidar for measuring SO2 in plumes from fossil fuelled power stations is examined. The potential of the technique is investigated for the measurement of SO2 close to power station stacks and in situations where the long range t

A new remote technique for range-resolved gas detection is described: photoacoustic detection and ranging (PADAR). The technique involves sending out a laser pulse tuned to an absorption line of the gas. When the pulse hits a localised concentration

Methods of measuring the concentration of atmospheric pollutants by laser absorption spectroscopy, such as differential absorption lidar (DIAL) and integrated long-path techniques, all rely on the validity of Beer’s exponential absorption law. It i
