Currently available semiconductor lasers for spectroscopy in the near- and mid-infrared region based on direct band-to-band transitions as gallium-arsenide, indium-phosphide, antimonides and lead-salt containing compounds will be discussed together with the main features of different tunable diode-laser absorption spectrometers for trace gas analysis. Measurements of atmospheric carbon dioxide ...
In recent years, the narrow bandgap antimonide based compound semiconductors (ABCS) are widely regarded as the first candidate materials for fabrication of the third generation infrared photon detectors and integrated circuits with ultra-high speed and ultra-low power consumption. Due to their unique bandgap structure and physical properties, it makes a vast space to develop various novel devic...
The current status of III-V tunable diode lasers (TDLs) emitting between 1 -5pm wavelengths for spectroscopy and chemical analysis is described. Single mode distributed feedback (DFB) strained layer lnGaAs(P) lasers grown on lnP substrates with emission wavelength from 1.2 to 2.06 pm have been developed at JPL. DFB ridge waveguide lasers at 2,06pm have operated continuous wave (CW) up to 50°C w...
