Parameter changes of gaussian beams after passing through astigmatic lens 高斯光束通過像散透鏡后光束參數(shù)的變化
Based on the generalized huygens - fresnel diffraction integral and in consideration of the effect introduced by astigmatism , the transformation properties of gaussian beams passing an astigmatic lens are studied analytically , the beam quality of astigmatic gaussian beams is analyzed in terms of the beam propagation factor ( m2 - factor ) and power in the bucket ( pib ) , and illustrated with numerical examples 基于廣義惠更斯-菲涅爾衍射積分,并考慮了像散的影響,對高斯光束通過像散透鏡后的傳輸特性作了解析研究,以光束傳輸因子和桶中功率為參數(shù)分析了像散高斯光束的光束質(zhì)量,并以數(shù)值計算例加以說明。
