Simple equations used to study the wavelengths of two-segment bistable diode lasers.
The physical fact that the competition between modes in homogeneously broadened media will eventually settle the overall gain down to the threshold level has been turned into an extra equation for the mathematical study of the wavelength-dependent rate equations applicable to two-segment bistable diode lasers. This has made the simultaneous determination of bistable laser operation parameters including the wavelength much simpler. Calculations of laser wavelength indicate that the switch-on and switch-off processes are accompanied by upward and downward wavelength chirps, respectively.
