摘要:

我们提出了一个窄线宽连续激光源,在780 nm的输出功率超过11瓦的基础上,放大的1560 nm光纤激光器的单程倍频效率为36%。该源集高功率、简单性、模式质量和稳定性于一体。在没有任何主动稳定的情况下,测得线宽低于10kHz。该光纤种子可调谐频率超过60 GHz,可以探测到87 Rb和85 Rb的D2跃迁,为激光冷却和原子干涉测量中的大动量转移分束器提供了一种可行的高功率源。这种类型的源将为新一代高通量,高占空比简并量子气体实验铺平道路。

英文摘要:

We present a narrow linewidth continuous laser source with over 11 Watts of output power at 780nm, based on single-pass frequency doubling of an amplified 1560nm fibre laser with 36% efficiency. This source offers a combination of high power, simplicity, mode quality and stability. Without any active stabilization, the linewidth is measured to be below 10kHz. The fibre seed is tunable over 60GHz, which allows access to the D2 transitions in 87Rb and 85Rb, providing a viable high-power source for laser cooling as well as for large-momentum-transfer beamsplitters in atom interferometry. Sources of this type will pave the way for a new generation of high flux, high duty-cycle degenerate quantum gas experiments.
