利用以四阶运行的电泵浦单异质结构 GaAs/GaAlAs 分布式反馈激光二极管，我们获得了高度准直的激光束，该激光束垂直于 p−n 结平面耦合输出，而不是通过劈裂端镜。发现该光束在由光栅确定的尺寸上具有 0.35° 的角发散度，并且实际上 100% 偏振，E 矢量平行于波纹反馈结构的凹槽。
Utilizing an electrically pumped single−heterostructure GaAs/GaAlAs distributed−feedback laser diode operating in fourth order we have obtained a highly collimated laser beam which is coupled out normal to the plane of the p−n junction rather than through the cleaved end mirrors. This beam is found to have an angular divergence of 0.35° in the dimension determined by the grating and is virtually 100% polarized with the E vector parallel to the grooves of the corrugated feedback structure.
