A theoretical consideration is presented of the optical coupling and selection of laser array modes by the use of a developed Lummer-Gehrcke interferometer as a resonator reflector. Control of the mirror reflection of the proposed interferometer permits laser power to be redistributed through channels on the outlet resonator mirror; in particular, it makes it possible to lead power out of the resonator by a single beam. In this way it is possible to diminish the sidelobes in the far-field radiation profile of multichannel lasers and to raise the efficiency of the optical coupling of the laser array with waveguides and fibers. This method may be used for the redistribution of laser power on the outlet mirror in striped lasers as well.
本文提出了一种理论思考，即通过使用已开发的Lummer-Gehrcke干涉仪作为谐振器反射器来实现激光阵列模式的光学耦合和选择。所提出的干涉仪的镜面反射控制允许激光功率通过输出谐振器镜面上的通道重新分配；特别是，它使得通过单束光将功率引出谐振器成为可能。通过这种方式，可以减少多通道激光器远场辐射分布中的旁瓣，并提高激光阵列与波导和光纤的光学耦合效率。该方法也可用于条纹激光器输出镜上激光功率的重新分配。
