论文摘要
我们展示了一种简单的方法，可以通过GHz级可编程调制带宽和瓦特级输出功率获得准确的光波形，以实现自由原子和分子的宽带光学控制。任意振幅和相位调制通过低功率光纤电流调节器从微波炉转移到光线。亚米瓦特光学边带通过锥形半导体放大器（TSA）以功率平衡的方式与光载体共扩散。通过以准连续的方式自动保持TSA接近饱和，可以有效抑制与脉冲高增益扩增相关的典型噪声通道。作为一个示例应用，我们证明了两个具有相干纳秒脉冲的rubidium同位素的相互交织的冷却和捕获。
We demonstrate a simple method to obtain accurate optical waveforms with a GHz-level programmable modulation bandwidth and Watt-level output power for wideband optical control of free atoms and molecules. Arbitrary amplitude and phase modulations are transferred from microwave to light with a low-power fiber electro-optical modulator. The sub-milliWatt optical sideband is co-amplified with the optical carrier in a power-balanced fashion through a tapered semiconductor amplifier (TSA). By automatically keeping TSA near saturation in a quasi-continuous manner, typical noise channels associated with pulsed high-gain amplifications are efficiently suppressed. As an example application, we demonstrate interleaved cooling and trapping of two rubidium isotopes with coherent nanosecond pulses.
