光束腰半径
Examples
- Starting with analysis on the field of gaussian feed ' s aperture , the relations of radiation characteristic and power capacity and gaussian beam waist radius are investigated particularly by using the circular waveguide intrinsic mode expansion method
<中文摘要> =本文从圆锥高斯馈源口面场分析入手，利用高斯场展开成规则圆波导场的方法，细致的讨论了高斯束腰对馈源辐射特性和功率容量的影响。 - The task will be completed by designing 3mm quasi - optical resonator to get small waist radius of gaussian beam existing in quasi - optical resonators . the 3mm quasi - optical resonator test system is built and the test soft is written in vc + + language . we test on dielectric plates , then realize sweep test of large - area sample by adjusting move set to get dielectrical parameter distribution
本课题拟通过设计3mm开放式谐振腔,使开放式谐振腔中传播的高斯波束的束腰半径尽可能小,组建3mm准光学谐振腔测试系统,编写测试软件,对介质片进行测试,调节移动装置,实现对大面积介质片的扫描测试,从而测得介质片介电性能的分布。 - On one hand , is the product of beam waist radius and half divergence angle , wavelength is not involved . so there is possibility to compare the acutal focusing ability among laser beams with different wavelength . on the other hand , is a calculated result by measuring experiment , and it is more brief and persuadable than m 2factor , since the latter one is a ratio with basic mode gauss beam
论文研究论证了用值评价激光光束质量的实际意义在于两个方面,一方面它仅仅包含了光束束宽和发散角,不涉及波长的因素,使不同波长激光束的可加工能力具有可比性;另一方面,值是根据对光束传输路径上不同位置处束宽实际测量结果的计算值,比其在与基模高斯光束进行比值计算得到的m2因子更简洁、更有说服力。 - The electromagnetic field and energy distribution of gaussian beam existing in quasi - optical resonator are analyzed and simulated using matlab , the resonant frequency and waist radius of the resonator are calculated , and design the 3mm quasi - optical resonator according to resonant frequency and waist radius
本文首先分析了准光腔内存在的高斯波束电场和能量分布情况,模拟了工作模式tem _ ( 00q )和高次模式的电场和能量分布图,计算准光腔的谐振频率和束腰半径,以此为依据设计了3mm准光学谐振腔。
