本實驗利用雙折射擴散接合晶體Nd:YVO4/ Nd:GdVO4以及ABCD矩陣計算穩定區範圍，設計四面鏡共振腔來產生雙波長特性之圓柱向量光，並且同時擁有光學渦流特性。藉由改變穩定區位置，調控圓柱向量光的產生，並分別得到雙波長方位角偏振光以及雙波長徑向偏振光。雙波長分別為1063.14nm以及1065.54nm。並且量測其偏振度DOP(degree of polarization)確認偏振特性良好以及量測光束品質因子(M-squared)。並利用馬赫-曾德爾干涉儀((Mach-Zehnder interferometer))量測其雙波長圓柱向量光以及其分解之模態皆擁有一股渦流之光學特性。最後利用分解之兩模態與自己干涉以及與對方干涉之結果驗證此系統之圓柱向量環形光之偏振方向單一且乾淨，符合理論。

In this thesis, we studied the generation of dual-wavelength cylindrical vector beams in a system of diffusion-bonded crystal Nd:YVO4/ Nd:GdVO4 and four element cavity calculated through ABCD law. By adjusting the position of stable range, we can manipulate the output beam to be azimuthally- or radially-polarized. The dual wavelengths of the output beams are 1063.14 nm and 1065.54 nm which are generated by Nd:YVO4/ Nd:GdVO4. The high percentage of DOP indicate that polarization quality is good, and the beam quality factor M2 was measured by different spot size of propagation distance and the results of Mx2 and My2 are little bigger than theoretic value. Moreover, the output beam with characteristics of vortex were verified by Mach-Zehnder interferometer. I found that whether dual-wavelength cylindrical vector beams or the decomposition modes HG10 and HG01, the topological charges l were 1. The pure direction of decomposition modes were also verified by Mach-Zehnder interferometer.
