Paper Abstract

A Cd diffusion technique applicable to PbSnSe, PbSSe and PbCdS is presented. The pn-junc-tions of these diffused diodes are characterized by EBIC. The two important laser properties - maximum operation temperature and maximum output power - are discussed in detail. The large continuous tuning range of the diodes make them useful for integrative or derivative spectroscopy methods. An apparatus containing a laser source assembly for eight different diode lasers in a single closed cycle refrigerator unit, a polychromator for mode selection and beam combination and a two path measuring cell is described. Test results on simultan-eous CO and CO2 real time concentration measurements using integrative spectroscopy are presented.
