Single-shot thermometry with dual-broadband rotational coherent anti-Stokes Raman spectroscopy that employs amplified spontaneous emission from a broadband modeless dye laser has been examined. Evaluation of single-shot spectra of air, N2, and O2 showed an improved temperature precision at room temperature compared with the precision obtained with a conventional dye laser. A comparison was also made between the use of single-mode and multimode Nd:YAG lasers as sources for narrowband radiation, and in all cases the single-mode Nd:YAG laser resulted in higher precision. The experimental results are compared with theoretical predictions.
对采用宽带无模染料激光器的放大自发辐射的双宽带旋转相干反斯托克斯拉曼光谱单次测量温度的方法进行了研究。对空气、氮气和氧气的单次光谱评估表明，与传统染料激光器相比，在室温下温度精度有所提高。还对使用单模和多模Nd:YAG激光器作为窄带辐射源进行了比较，在所有情况下，单模Nd:YAG激光器都具有更高的精度。将实验结果与理论预测进行了比较。
