Spectral Output of Homogeneously Broadened Semiconductor Lasers

Gain, spontaneous emission, and reflectance play important roles in setting the spectral output of homogeneously broadened lasers, such as semiconductor diode lasers. This paper provides a restricted-in-scope review steady-state properties Analytic but transcendental solutions for simplified set equations propagation modes through gain section are used to create Fabry–Pérot model laser. is explain lasers without need guiding-enhanced capture population beating, or non-linear interactions. It shown that amount emission resonant enhancement reflectance-gain (RG) product embodied presented explains observed output. The caused by intentional unintentional internal scattering external feedback.
