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

We report on an experimental investigation of the possibility to correlate diode laser gas transmission spectra to computed or previously measured spectra. Spectral correlation of this kind could profitably be applied in automated gas analyzers in or
