摘要
研制了基于单脉冲CARS方法的温度测量装置,使用宽带染料激光器产生线宽200cm-1的斯托克斯光,一次脉冲就可以得到完整的CARS光谱,实现了温度的瞬时测量。
Coherent Anti-stokes Raman Scattering （CARS） technology measured temperature through pulses cumulation of pump laser in the past decades. The measurement period was up to ten seconds or even longer. This method will cause relative large error once used in unstable temperature field diagnosis. Based on single-pulse CARS technology, the temperature measurement appliance which introduced broadband laser source （ 〉 200cm^-1 ） was developed. The appliance can get the whole CARS signal spectrum during a pulse width and measure the temperature instantaneously.
