我们讨论了三种方法，将两束线偏振相等、频率间隔非常近的激光组合成一束输出光束，每束光束的输入功率最高可达100%。其中详细介绍了一种改进型马赫-曾德尔干涉仪，它允许在一个简单的伺服回路的帮助下以电子方式调节组合输出功率。使用现成的光学组件，我们获得了98%的效率。
We discuss three ways to combine two laser beams with equal linear polarizations and very closely spaced frequencies into a single output beam containing up to 100% of the input power of each beam. One setup, a modified Mach–Zehnder interferometer, is examined in detail; it allows to adjust the combined output power electronically with the help of a simple servo loop. With off-the-shelf optical components we obtained a 98% efficiency.
