| 1. | Gvd ( gnu visual debugger ) is a general purpose graphical debugger frontend Gvd是一个通用目的的图形调式前端。 |
| 2. | Gvd works with native and cross - debuggers and can handle several languages in the same debugging session and the same application 它本地工作,交叉调试并且能在相同调试部分和相同应用中处理几种语言。 |
| 3. | The achievements gained in this thesis are as follows : ( 1 ) sc generation from optical fibers with different gvd is simulated in detail 主要工作内容如下: ( 1 )研究了不同色散特性的常规色散位移光纤和正常色散平坦光纤中超连续谱产生情况。 |
| 4. | The study based on self phase modulation mechanism and the effects of gvd on sc generation are mostly focused on by analyzing and calculating theoretically 本文主要研究群速度色散对光纤中自相位调制效应sc谱展宽的影响,分析了产生sc谱的物理机制。 |
| 5. | The origin of supercontinuum ( sc ) generation in optical fibers has been conjectured to be the interplay between fiber nonlinearities ( self phase modulation , cross phase modulation and raman self scattering ) and group - velocity dispersion ( gvd ) 光纤中超连续supercontinuum ( sc )谱的产生源于光纤中各种非线性效应(自相位调制效应、交叉相位调制效应,四波混频效应及受激raman散射等)和群速度色散的共同作用。 |
| 6. | 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 并采用“天光一号”电子束泵浦krf激光器进行紫外超短脉冲激光的进一步放大,获得能量2 3j 、脉冲宽度约1 . 2ps的紫外超短脉冲激光输出,激光功率达到2tw 。 |
| 7. | We derive an analytic expression of the group velocity dispersion ( gvd ) induced chirp and the self - phase modulation ( spm ) induced chirp in the normal dispersionregion of non - kerr - like optical fibers with saturable nonlinarity . the evolution of chirp is simulated by numerical methods . the studied results show that the more powerful saturable effects , the smaller is chirp and the gently is chirp . the net chirp is zero in the central region of the pulse 从理论上推导出具有饱和非线性的非克尔光纤正常色散区内,群速度色散效应导致的啁啾和自相位调制效应导致的啁啾解析表达式.利用数值解法模拟了非克尔光纤正常色散区啁啾演变过程.研究结果表明:当非克尔光纤的饱和非线性增强时,净啁啾不断减小,而且,越来越平缓,脉冲中心附近区域净啁啾接近零 |
| 8. | The origin of supercontinuum spectrum ( sc ) generation in optical fibers has been shown to be the interplay between fiber nonlinear effects ( such as self phase modulation , cross phase modulation , stimulated raman scattering and stimulated brillouin scattering etc ) and group - velocity dispersion ( gvd ) 光纤中超连续谱supercontinuumspectrum ( sc )的产生源于光纤中各种非线性效应(如自相位调制效应、交叉相位调制效应,四波混频效应、受激raman散射与受激brillouin散射等)和群速度色散共同作用。 |
| 9. | It is found that flat and wideband sc ca n ' t be obtained in common dispersion - shifted fiber , and dispersion - flattened fiber with small normal gvd is most suitable for flat and wideband sc generation ( 2 ) sc generated in dispersion - flattened / decreasing fiber is studied profoundly 结果表明,利用自相位调制效应在常规色散位移光纤一般不能产生平坦、宽带的sc谱。具有较小正常色散的色散平坦光纤有利于平坦、宽带sc谱的形成。 ( 2 )研究了色散平坦渐减光纤中sc谱的产生。 |
