摘要 对使用高斯 -贝塞耳 (GB)光束的Z -扫描技术理论进行了研究 ,结果发现 :理想高斯光束即使有一个很小偏离 ,也会导致测量灵敏度的显著变化 ;用一个小的贝塞耳光束调制高斯光束 ,Z -扫描的灵敏度比用常规的高斯光束增加 40倍以上 . A theoretical study on Z_scan technique using Gaussian_Bessel beams is reported. It is found that even the slightest deviation from a perfect Gaussian beam can change the sensitivity of the Z_scan measurements significantly and that using a small Bessel profile to modulate Gaussian beams can increase the Z_scan sensitivity 40 times more than using conventional Gaussian beams.
