摘要

金刚石氮-空位（nitrogen vacancy，NV）色心测温技术是一种新兴的量子测温方法，具有超高灵敏与稳定物化性质，通过基态能级零场劈裂实现对温度测量，可用于芯片、生物体等多领域温度监测。一般使用激光激发电子自旋、期间施加微波进行操控，进而获得NV色心的光学探测磁共振（optically detected magnetic resonance， ODMR）谱，然而在进行ODMR谱线测量时，激光功率波动会引起荧光光子数波动。为从根源上抑制激光功率波动，基于液晶相位延迟器（liquid crystal variable retarder， LCVR）设计了一种适用于金刚石NV色心传感器的激发激光闭环稳定控制模块。长期稳定性测试显示，闭环控制后激光功率稳定性较原始光功率抑制倍数达到5.6倍。经优化LCVR设定电压，在室温下进行ODMR实验对比，开启闭环控制后，零场分裂能D值测量标准偏差从204.02 kHz降至47.03 kHz，证实该激光稳定闭环控制方法提升了荧光光功率及谱线测量稳定性。

Abstract

Thermometry based on nitrogen-vacancy （NV） centers in diamond is an emerging quantum temperature sensing technique characterized by ultra-high sensitivity and stable physico-chemical properties. This method primarily measures temperature through the zero-field splitting of the ground state energy levels. It is applicable for temperature monitoring in various fields， including chip technology and biological systems. Typically， this technique involves exciting the electron spins of NV centers using a laser， applying microwaves for manipulation， and subsequently acquiring the optically detected magnetic resonance （ODMR） spectra of the NV centers. However， during ODMR spectral measurements， fluctuations in laser power result in variations in the fluorescence photon count. To fundamentally suppress laser power fluctuations， a closed-loop stabilization control module for the excitation laser was developed based on a liquid crystal variable retarder （LCVR）， making it applicable for diamond NV center sensors. A long-term stability test was conducted， and after closed-loop control， the laser power stability was suppressed by a factor of 5.6 compared to the original optical power. Finally， the set voltage of the liquid crystal phase retarder was optimized， and ODMR experiments were conducted at room temperature for comparison. After enabling closed-loop control， the standard deviation of the zero-field splitting energy D value measurement decreased from 204.02 kHz to 47.03 kHz， demonstrating an improvement in the stability of fluorescence intensity and ODMR spectral measurements.
