Weboperation of semiconductor lasers. 11.4.2 Laser Output Power: We also need expressions for the light coming out of the laser. Photons leave the cavity in two ways; they can either escape from the end facets (or mirrors) or they can get absorbed by the cavity. Only the photons that leave the cavity from the mirrors constitute useful output.
