中文摘要	we have determined the far-field patterns and beam parameters of vertical-cavity surface-emitting lasers (vcsels) with different structures. the results show that the window diameter and the active-layer aperture of vcsels strongly influence laser far-field distributions and beam characteristics; for vcsels with small window omega=5 mu m, only one dominant lobe has been observed in the far-field profiles, even though injected current was increased up to 2 ith; and the smaller the ratio of the window diameter to the active-layer aperture, the larger is the far-field divergence. the laser structure dependence of the k factor has also been studied.
