bessel beam

基本解释

It is proved by theoretically analysis and numerical calculations, that low rank Bessel beam is stable in the multiple pass ring resonator.
理论分析和迭代法数值计算表明，低阶贝塞尔光束是适合多程环形腔的稳定模式；
Under appropriate conditions a [Bessel beam] can act as an ‘optical tractor beam,’” write physicist Jun Chen of Fudan University in Shanghai and colleagues.
在合适的条件下，贝塞尔光束可以作为一种光学牵引束。” 复旦大学物理学家陈俊（Jun Chen,音译）和他的同事们在文章中写到。
Results show that if the cross-section of the axicon is ideally manufactured in circular symmetry, the field distribution behind the axicon is approximately an ideal Bessel beam.
计算结果指出，当轴棱锥的截面为圆对称的理想加工时，轴棱锥产生的光场分布为近似理想的零阶贝塞耳光。
