spot size

基本解释

The spot size of laser and its beam waist is the important parameter for assessing the performance of lasers.
激光光斑尺寸和激光束腰光斑尺寸是衡量激光器性能的重要参数。
The analyses and calculations show that the intensity of spot, spot size and sidelobe intensity oscillate with the thickness of the film.
分析和计算指出，光斑的强度、边瓣强度和光斑大小随薄膜的厚度发生振荡。
Furthermore, microscope objective must exactly correct spherical aberration and laser is desired the operation with fundamental mode for obtaining small focusing spot size.
而且，为了获得小的聚焦光斑尺寸，物镜必须严格校正球差，并且激光器应是基模运转的。

If I want to move this stack here, I'm going to take a stack of size n minus 1 move it to the spare spot, now I can move the base disk over, and then I'm going to move that stack of size n minus 1 to there. That's literally what I did, OK?
如果我想移动这些圆盘，我先把从n-1个圆盘1,移动到多余的柱子上去，这样我就能把最底下的圆盘放到这儿了，然后再把从n-1个圆盘放到这儿来,这就是确切的我怎么做的对不对？

The key to cracking that nut is apparently the new thermal assisted optical element Fujitsu's developed, allowing for an ultra-tiny sub-hundred nanometer optical spot size, which in turn should enable recording on the one terabit (not byte, let's not get crazy here) per square inch level.
