The information of optical gain of semiconductor lasers can be obtained through the amplified spontaneous emission from double facets. By utilizing this new approach, an experimental research about polarization (TE and TM) gain characteristics of continuously-operated 808 nm GaAs/AlGaAs quantum well laser is introduced in this paper. Through the measured gain spectra which are compared with the theoretical gain curves, we analyze the variations of hole subband corresponding to the polarizations along with the change of injection current, meanwhile the actual status of gain spectra and influential factors of the continuously-operated laser are discussed as well.
