论文摘要
光学频率梳子是精确测量实验的必不可少的工具,从远程光谱传感到痕量气体的应用到光原子时钟的表征和比较,以进行精确的时间保存以及超越标准模型以外的物理学。在这里,我们描述了基于ER/YB共掺杂的玻璃增益介质的自由空间激光器,并完全表征了电信波段,自模型频率梳子。激光提供了ER:基于纤维激光的频率梳子的强大且具有成本效益的替代方案,同时提供类似于Ti:蓝宝石激光系统的稳定性和噪声性能。最后,我们使用两个超稳频率合成中的ER/YB:玻璃频率梳子的实用性,使用两个超稳定的光学参考在1157 nm和1070 nm和1070 nm以及低噪声光子微波生成中,通过将这些引用分配给微波域。
Optical frequency combs are an essential tool for precision metrology experiments ranging in application from remote spectroscopic sensing of trace gases to the characterization and comparison of optical atomic clocks for precision time-keeping and searches for physics beyond the standard model. Here we describe the architecture and fully characterize a telecom-band, self-modelocking frequency comb based on a free-space laser with an Er/Yb co-doped glass gain medium. The laser provides a robust and cost-effective alternative to Er:fiber laser based frequency combs, while offering stability and noise performance similar to Ti:sapphire laser systems. Finally, we demonstrate the Er/Yb:glass frequency comb's utility in high-stability frequency synthesis using two ultra-stable optical references at 1157 nm and 1070 nm and in low-noise photonic microwave generation by dividing these references to the microwave domain.
