The main factors limiting to optical fiber transmission of high power laser pulse is pointed  including air breakdown at focus area and surface damage of optical fiber. The theory of air breakdown and the fiber coupling conditions is described briefly. The results of study to the transmission properties and damage conditions are presented on the basis of four different types of optical fibers. The results of the experiments are further analyzed in the aspects of transmitting efficiency  air breakdown and surface damage. The local and foreign optical fibers  with plastic-cladding and silica-cladding  and step- index and graded- index fibers are tested separately in the experiments. The experiments showed that the imported fibers are able to transmit up to 10MW peak power laser pulse with no any visible damage  while energy density at the fiber output end surface is 3.54GW/cm2. For local fibers  damage on the input surface of both plastic-cladding and silica-cladding  step-index fibers was found obviously. The column damage to the graded index fiber was also found and investigated in the research. Damage mechanisms of fiber at high peak power laser pulses are summarized. High quality finishing of fiber end surface will improve damage threshold tremendously. The conclusion of the study is that transmitting Q-switched Nd:YAG pulses of 10MW peak power is feasible for the domestically made fibers if their end surfaces are properly processed.   Thiophene-fluorene derivatives with high three-photon absorption activities and their application to optical power limiting 期刊论文  OAI收割 chin. phys., 2006, 卷号: 15, 期号: 4, 页码: 750, 755 马文波; 吴谊群; Han JH; Liu JH; 顾冬红; 干福熹 收藏  |  浏览/下载：2020/231  |  提交时间：2009/09/22 three-photon absorption  thiophene-fluorene derivative  AM1  optical power limiting   两种新型芴类衍生物的三光子吸收特性研究 期刊论文  OAI收割 物理学报, 2005, 卷号: 54, 期号: 8, 页码: 3698, 3702 马文波; 吴谊群; 韩俊鹤; 顾冬红; 干福熹 收藏  |  浏览/下载：2097/262  |  提交时间：2009/09/22 三光子吸收  fluorene-based derivatives  衍生物  three-photon absorption  特性研究  optical power limiting  N-二甲基甲酰胺  nonlinear transmission  YAG脉冲激光  芴  乙基已基  光限幅效应  化合物  荧光行为  脉冲宽度  重复频率  吸收性质  区域覆盖  中心波长  吸收系数  入射光强  新材料  甲氧基  乙烯基  单光子  吸收峰  荧光带  透过率
