| 摘 要： | 以三次谐波自相关测量原理为出发点,研究了其和频过程中BBO晶体的表面散射杂散光。详细推导了由晶体表面散射引入的杂散光的具体表达式,定量分析了其对和频过程中输出信号的对比度的影响。分析表明,杂散光强度与晶体表面粗糙度有一定的关系。晶体表面粗糙度为激光波长的1%时,引入的杂散光噪声约为10-8。表面越光滑,引入的噪声越小。

| Abstract: | We analyze the stray light caused by surface scattering of the sum-frequency crystal in third-order correlation measurement and its influence on the contrast of the sum-frequency light. Besides, the expression of the stray light caused by surface scattering is given. When the surface roughness is 1% of the laser wavelength, the intensity of stray light reaches about 10-8. And the rougher the surface is, the more stray light it causes. |
