  1. This thesis was divided into eight chapters, and the main results and innovations obtained here can be summarized as follows : ( 1 ) the physics model of tsrs in frequency conversion crystals has been built up firstly. based on quantum - mechanical viewpoints and the following physical processes and parameters : the two - photo interaction of light with matter, paraxial diffraction of stokes, langevin noise sources, reflection at the faces and the edges of crystals, gain coefficient, beam aperture, pulse width and fluence of 3, the physics model of tsrs in kdp and kdp crystals acting as high - fluence frequency convector and the paraxial operator maxwell - bloch - langevin equations have been built up

    全文共分八章，取得的主要成果及創新點如下： （ 1 ）首次建立了諧波轉換晶體的tsrs物理模型本文根據量子力學原理，在考慮如下物理過程和參量的基礎上：光與物質的雙光子相互作用； stokes光的傍軸衍射； langevin （郎茲萬）噪聲源；晶體表面反射和端面反射；增益系數、光束口徑、脈寬和三倍頻光能量密度，推導出高通量激光在kdp和kd ~ * p諧波轉換晶體中的tsrs物理模型和空間上的近軸算符maxwell - bloch - langevin方程組。
  2. And this result is extended to the eigenfunction of maxwell ' s equations. then the mode series of step index planar dielectric waveguide and circular optical fiber are studied, including propagation modes and radiation modes. as application, there are three examples : the emergent wave from planar waveguide to free space, the transverse and longitudinal coupling of waveguide and the measurement of scalar gratings

    由於從一個空間到另外一個空間的光束傳播伴隨著界面上各個模式能量之間的耦合，作為應用，本文介紹了完備性在三個情況下的應用：平面波導出射光束的衍射性質、波導的橫向和縱向耦合以及標量光柵的測試。
  3. In fact, hartmann - shack wavefront sensor is affected by the noise of ccd and the constructed error too. in our compare, a bridge is setup, which is the original wavefront composed by zernike polynomial, we transform the original wavefront into far field. then we can compare the accuracy of hartmann - shack wavefront sensor with the accuracy of the system of far field diagnosis in detecting the farfield, using diffraction limit and encircle energy

    我們在進行兩者相互比較的過程中，搭建了一個比較的橋梁，即由zernike多項式組成的各種原始像差波前，將它也變換到遠場作為原始理想遠場光斑，然後，以它的衍射極限和環圍能量曲線作為評價標準，比較hartmann - shack波前傳感器和遠場測量系統在光束質量診斷中的探測精度。
  4. The tuning curve of type - i phase matching of bbo opo are measured with accuracy ; the maximum conversation in total of the system is about 31 % at 615. 6 nm, and it is fitted well with the gtp formula ; in the end we compared the output linewidth and unstable cavity far field beam qua lity of the bbo opo under the condition of type - i phase matching and type - ii phase matching, it is proved that we can obtain the parametric output of linewidth less than 0. 3 nm and the beam divergence angle approaching diffraction limits by take the advantages of type - ii phase matching and unstable cavity designs

    測量了該系統的轉換效率最大為31 ，並能與理論公式極好地吻合，最後比較了在類相位匹配條件下和類相位匹配條件下的bbo - opo的輸出線寬，以及非穩腔的遠場光束質量，實驗結果表明，利用類相位匹配以及非摘要穩腔設計可以獲得線寬小於0 3nlm 、光束發散角接近衍射極限的參量光輸出。
