摘要 采用啁啾脉冲堆积的方法获得平顶宽脉冲,根据波包传输近似方程,数值模拟了堆积脉冲在线性介质中的传输特性,给出了初始堆积子脉冲延迟引入不同初始位相差和不同啁啾量情况下堆积脉冲时间波形传输的演变规律。结果表明,子脉冲间距差引入的初始延迟参数的细微变化就会引起初始位相差的显著变化,导致堆积脉冲包络相对子脉冲延迟参数不稳定;包络脉冲的特性与子脉冲的载频、脉冲形状、脉宽和啁啾量等子脉冲参数,及子脉冲间的延迟参数等有关;啁啾越大、子脉冲初始脉宽越短、传输介质色散系数越大,则传输后的堆积脉冲时间调制变化越严重。 The flat topping width pulses are obtained by the method of twitter pulse stack. According to the approximately equation of the pulse transmission equation, the transmission characteristic of the stack pulse in linear medium have been analyzed theoretically, and the time profile change rule of the tack pulse are given. It is show that the stack pulse envelope antithetical couplet pulse delay parameter is unstable. If the twitter is greater, the sub-pulse initial pulse width is shorter, and the transmission medium dispersion coefficient is bigger, then the stack pulse time modulation become more serious after the transmission.
