Spectral characterization of multimode lasers 多模激光器的光譜特征
Starting from the propagation law of partially coherent light and using a typical partially coherent light , i . e . , gaussian schell - model ( gsm ) beam describing the multimode laser in practice , i present in this dissertation the research results on vectorial partially coherent light , spectral changes of partially coherent light passing through optical element , spectral switch of partially coherent light diffracted by an aperture , and the spectral anomaly of diffracted fully spatially coherent light by an aperture 本文從部分相干光的傳輸理論出發(fā),以模擬實際多模激光的一類典型部分相干光? ?高斯-謝爾模型( gsm )光束為主要研究對象,對矢量部分相干光、部分相干光通過光學元件的光譜變化、被光闌衍射的部分空間相干光的光譜開關(guān)和被光闌衍射的完全空間相干光的光譜異常等現(xiàn)象進行了深入研究。
