AI 中文摘要
我们描述了一种校准声光调制器（AOM）响应的方法，以实现对光场强度和频率的精确、任意控制。该方法包括表征AOM对其输入射频驱动电压的非线性响应，并应用迭代校准/校正算法，将输入射频幅度和频率驱动准确映射到输出光强度和频率偏移。经过几次校准/校正迭代后，AOM的校准可在相对宽的频率调谐范围（约100 MHz）内将光功率维持在恒定目标值的1%以内，相对偏差σ=0.2%。我们将该校准方法用于生成可编程波形和具有定制强度与频率轮廓的光脉冲，这些轮廓与目标规格高度匹配。该技术为需要高精度光调制的应用提供了一种简单且鲁棒的方法。
英文摘要
We describe a method for calibrating the response of an acousto-optic modulator (AOM) to enable precise, arbitrary control of the intensity and frequency of optical fields. The method involves characterizing the nonlinear response of the AOM to its input RF drive voltage and applying an iterative calibration/correction algorithm to accurately map input RF amplitude and frequency drive to output optical intensity and frequency shifts. After a few calibration/correction iterations, the calibration of the AOM maintains the optical power within 1$\%$ of a constant target value over relatively wide frequency tuning range ($\approx$100 MHz), with $σ=0.2\%$ relative deviation. We apply this calibration method to generate programmable waveforms and optical pulses with tailored intensity and frequency profiles that closely match their target specifications. This technique offers a simple and robust method for applications that require high-accuracy optical modulation.
