  1. Our results show that pmd induces pulse broadening randomly in high bit - rate optical fiber communications ; the synchronous amplitude modulation control may correct directly any position change of timing jitter and soliton interaction, so the transmission distance and pulse quality will increase further

    研究結果表明對于高速率傳輸系統， pmd對脈沖的影響在時域上表現為脈沖形狀的展寬，這種展寬是隨機的；而同步幅度調制是在時域上，將發生形變的脈沖通過振幅調制，恢復原形，從而提高脈沖的傳輸性能。
  2. We have calculated and plotted the curves of the refractive index, group velocity index, lowest - order and second - order dispersion indexes as a function of wavelength. the lowest - order and higher - order dispersion - induced broadening and deforming of light pulses is analyzed for various pulse shapes, such as gaussian, super - gaussian and hyperbolic secant pulses

    給出了折射率、群速指數、低階和二階色散系數隨波長變化的關系曲線，研究了高斯脈沖、超高斯脈沖和雙曲正割脈沖等超短脈沖在clbo晶體中傳播時，由於低階色散和高階色散引起的脈沖展寬和形變。
  3. Numerical examples show that, pulse deformation and broadening, spectrum redshifting, narrowing and distortion take place with increasing diffraction angle in the near field, and the pulse form changes with propagation distance in the near field, but is preserved in the far field

    數值計算例說明在近場隨衍射角的增大會出現脈沖變形、加寬、譜紅移、變形、變窄等特性，脈沖形狀在近場隨傳輸距離變化而變化，但在遠場保持不變。
  4. In the picosecond and femtosecond time field, the durations of the pump and signal pulses are so short that special propagating characteristics of ultrashort pulse laser should be taken into account, especially the pulse broadening induced by the group velocity mismatch and the group velocity dispersion

    在皮秒和飛秒時域，由於泵浦光與產生的信號光的持續時間特別短，故在討論超短脈沖與物質相互作用時必須計及超短脈沖在介質中傳輸的特殊性質，尤其是群速失配與群速色散引起的脈沖展寬。
  5. As compared with the solution using pulse envelope representation, the propagation equation using complex analytic signal representation reveals different spatiotemporal behaviors such as spectrum redshifting, narrowing, and pulse broadening, etc. 2

    復解析信號解會出現光譜紅移、變窄、脈沖變寬等與脈沖包絡解不同的時空特性。
  6. With time - evolution - operator, it is proved that the population of upper level is in circumstance of cyclic oscillation by laser pulses pair of gaussian line - shape in a homogeneous broadening two - level system. the oscillatory time oxide is the delay time between the laser pulse pairs and the oscillatory frequency equals the one of transition between the lower and upper level

    引入時間演化算符，證明均勻增寬二能級體系在飛秒激光脈沖對作用下上能級激發態布居是周期性變化的，它以飛秒脈沖對之間的延時為時間軸，以該原子能級之間的躍遷頻率為振蕩頻率
  7. 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 。
