The pulses can be broadening and become negatively chirped while propagating in anomalous dispersive media. in normal dispersive media, the pulses can be broadening, positively or negatively chirped, or even the dispersion - free propagation can be achieved, if the beam and material parameters are suitably chosen
在負色散介質中傳輸時，脈沖會變寬、帶有負惆啾:而在正色散介質中傳輸時，脈沖會變寬、帶有正惆啾或負叨嗽，當光束和色散參數滿足一定條件時能實現「無衍射無色散」傳輸。 -
The 0 - 15kev energy slow - positron beam was used to measure the dopple broadening in sio2 / sic. both the s and w parameters clearly showed that the density of defect in sio2 layer had decreased after annealing in n2
利用0 - 15kev的慢正電子多譜勒能量展寬測試sio _ 2 sic的缺陷情況，發現不管是n型還是p型，氧化層附近其s參數經過n _ 2退火明顯減小， w參數在這個部位增大。 -
And the pulse duration was compressed from 420 to 220fs by compensated gvd broadening with prism pairs, the intensity achieved on target reached 1017w / cm2. furthermore, the 50mj uv pulse was boosted to 2 - 3j by e - beam pumped amplifier, the laser power reached as high to 2tw
並採用「天光一號」電子束泵浦krf激光器進行紫外超短脈沖激光的進一步放大，獲得能量2 3j 、脈沖寬度約1 . 2ps的紫外超短脈沖激光輸出，激光功率達到2tw 。
