我们从基于光纤激光器的光学频率梳中分离出单个齿，用于非线性光谱，从而直接参考频率梳。 89 MHz 铒光纤激光频率梳直接稳定在空芯光子晶体光纤内 (12)C(2)H(2) 的 P(23) (1539.43 nm) 泛音跃迁。为此，需要隔离单个梳齿并将功率从 20 nW 放大到 40 mW，并具有足够的保真度来执行饱和吸收光谱。距稳定齿约 7 nm 的梳子的分数稳定性在 100 ms 选通时间处显示为 6 × 10(-12)，这比参考 GPS 规范 Rb 振荡器的梳子的分数稳定性好一个数量级。
We have isolated a single tooth from a fiber laser-based optical frequency comb for nonlinear spectroscopy and thereby directly referenced the comb. An 89 MHz erbium fiber laser frequency comb is directly stabilized to the P(23) (1539.43 nm) overtone transition of (12)C(2)H(2) inside a hollow-core photonic crystal fiber. To do this, a single comb tooth is isolated and amplified from 20 nW to 40 mW with sufficient fidelity to perform saturated absorption spectroscopy. The fractional stability of the comb, ~7 nm away from the stabilized tooth, is shown to be 6 × 10(-12) at 100 ms gate time, which is over an order of magnitude better than that of a comb referenced to a GPS-disciplined Rb oscillator.
