论文摘要
我们演示了一个狭窄的780 nm激光系统,具有高达40 W功率和230 MHz的频率调制带宽。非线性光学元件上的有效重叠将两对相锁的频率组件结合到单光束中。用高质量的锯齿波形调制的Serrodrodne调制用于在数十MHz上以> 96.5%的效率进行频移。该系统通过交付同时进行的,较为明显的双光束拆分器,同时最大程度地减少自发发射,从而实现下一代原子干涉仪。
We demonstrate a narrow-linewidth 780 nm laser system with up to 40 W power and a frequency modulation bandwidth of 230 MHz. Efficient overlap on nonlinear optical elements combines two pairs of phase-locked frequency components into a single beam. Serrodyne modulation with a high-quality sawtooth waveform is used to perform frequency shifts with > 96.5 % efficiency over tens of MHz. This system enables next-generation atom interferometry by delivering simultaneous, Stark-shift-compensated dual beam splitters while minimizing spontaneous emission.
