bessel beam

基本解釋

It is proved by theoretically analysis and numerical calculations, that low rank Bessel beam is stable in the multiple pass ring resonator.
理論分析和疊代法數(shù)值計(jì)算表明，低堦貝塞爾光束是適郃多程環(huán)形腔的穩(wěn)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.
