| Abstract: | The beam quality of double-heterostructure injection lasers was studied based on non-paraxial vectorial moment theory developed by Porras.Some results we obtained after a series of calculation are different from conventional recognition on beam quality of semiconductor laser.It is also found its M2 factor could be less than 1 and has no lower bound for the active layer thickness da far less than wavelength λ |
