1·Supercontinuum is such an optical phenomena that when ultrashort pulses propagating in nonlinear media, its optical spectrum becomes very broad, much wider than that of the original spectrum.
超连续谱产生现象是指超短脉冲在介质中传输时由于介质的非线性效应导致脉冲的谱被极大地加宽，透视谱中产生了很多新的频率成分。
2·The phase reflection can influence the laser propagating in plasmas, such as the vacancy of laser field induced by two laser pulses counter-propagating in plasmas.
相位反射的发生会影响激光在等离子体中的传播，例如激光在等离子体中相对传播时会出现激光场空洞现象。
3·While picosecond optical pulses, for ultrashort pulses, it is needed to take into account the influence of high-order effects on the light's propagating in the medium.
而对于超短脉冲而言，就需要考虑包含高阶效应对光在介质中的影响。
