【摘要】 通过理论分析和实验结果，叙述了在宽带单脉冲相干反斯托克斯拉曼散射（ＣＡＲＳ）光谱测温技术中，利用光参量振荡器（ＯＰＯ）代替常用的染料激光器作为斯托克斯光源的可行性问题。理论分析指出，测温范围在２２００Ｋ以内，用ＯＰＯ作斯托克斯光源是可行的，并利用该实验装置实测酒精灯火焰中的温度分布，其结果与辐射温度计测量结果比较，误差在５％以内。更多还原

【Abstract】 A new more practical CARS thermormetry is set up using an optical parametric oscillator (OPO). The dye laser as a broadband Stokes soucre is replaced by the tunable OPO. Theoretical analysis and experiment demonstate that the new setup is useful in the case of measuring temperature below 2200 K, and it prossesses advantages compared to the conventional dye laser, such as tunable frequency, the stable output and spectral properties, the construction of a compact CARS system and so on.更多还原
