论文摘要
我们推出了一种强大的方法，可根据光学播种激光的输出束椭圆度的传感变化来稳定激光注射锁定。效果是由于播种机束和注入激光输出之间的干扰而产生的。我们证明了商业半导体激光器的方法，而无需对被使用的容易受到运行的注射激光系统进行任何内部更改。该方法还可以用来增加激光器的无模式调整范围，并有可能填补低噪声激光行业的空隙。
We unveil a powerful method for stabilization of laser injection locking based on sensing variations in the output beam ellipticity of an optically seeded laser. The effect arises due to an interference between the seeding beam and the injected laser output. We demonstrate the method for a commercial semiconductor laser without the need for any internal changes to the readily-operational injection locked laser system that was utilized. The method can also be used to increase the mode-hop free tuning range of lasers, and has the potential to fill a void in the low-noise laser industry.
