The condition, under which the paraxial approximation is valid, is given. 4. starting from the rayleigh diffraction integral, the propagation equation of ultrashort pulsed beams in dispersive media has been derived without making the paraxial approximation and slowly varying envelope approximation ( svea ), which allows for relatively large angles
從瑞利衍射積分公式出發，未作慢變振幅近似和近軸近似的條件下，導出了等衍射長度超短脈沖高斯光束在色散介質中非近軸傳輸方程，可用來處理色散介質較大角度的傳輸。 -
