非线性转换的英文
non-line conversion
例句与用法
- A hysteresis factor wasproposed to transform the multi - valued mapping of hysteresis into a one - to - one mapping which enabled neural networks to approximate the behavior of hysteresis
提出一个迟滞因子将多映射的迟滞非线性转换成能够被神经网络逼近的一一映射。 - Many opo implementations are limited by problems with conventional birefiingent phase - matched techniques in available materials , such as poynting - vector walk - off , low effective nonlinear coefficient , and inconvenient phase - matching temperature and angles
常规双折射位相匹配技术的opo有许多缺点，比如光束走离效应、非线性转换效率较低、位相匹配温度及匹配角的限制，阻碍了opo的发展。 - 4 . a brief analysis on frequency doubling at 852nm with bbo crystal has been presented . due to its relative small losses , theoretically it is supposed to get 50 % of conversion effi . ciency at a pump level of 600 mw by using a bbo crystal with cutting angle of 27 . 030 and length of 10mm
从分析其性能出发通过计算指出，使用bbo晶体获得倍频426nm蓝光(切割角度为27 . 430 ，长度为10mm ) ，虽其非线性转换系数小，但由于该晶体的损耗小，在泵浦功率约为600mw时。 - We analyze the generation of external cavity frequency - doubling with knbo3 crystal theoretically . in order to get the second - order nonlinear conversion from 858nm to 429nm with knbo3 , we use non - critical type - i phase - matching to avoid the walk - off effect the corresponding optimum focusing condition is as followings : double refraction parameter b = 0 , focus parameter = 2 . 84 , optimum phase mismatch parameter = 0 . 574 . based on the theoretical analysis and numerical calculations , we obtain the ideal nonlinear conversion coefficient about 1 . 45 % / w with crystal length of 7mm and 2 . 07 % / w with crystal length of 10mm at the phase - matching temperature around 23 . 50c
根据对其倍频原理及性能的分析讨论，在用该晶体完成波长从858nm到429nm的二阶非线性转换时，采用非临界相位匹配条件(此时无离散效应，对应的双折射参数b = 0 ，共焦长度为= 2 . 84 ，最佳相位失配因子为= 0 . 574 ) ，在相位匹配温度约为23 . 5时，理论上通过计算得到理想情况下非线性转换系数约为1 . 45 / w (长度为7mm ) ， 2 . 07 / w (长度为10mm ) 。
