Optical gain, absorption and spontaneous emission spectra for GaAs<sub>0.978</sub>Bi<sub>0.022</sub>/GaAs laser diodes are measured experimentally and compared with theory. Internal optical losses of 10-15 cm<sup>-1</sup> and peak modal gain of 24 cm<sup>-1</sup> are measured at threshold. The results of calculations showed excellent agreement with the experiment, key for future laser design.
