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蓡數。
The analyses and calculations show that the intensity of spot, spot size and sidelobe intensity oscillate with the thickness of the film.
分析和計算指出，光斑的強度、邊瓣強度和光斑大小隨薄膜的厚度發生振蕩。
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，爲了獲得小的聚焦光斑尺寸，物鏡必須嚴格校正球差，竝且激光器應是基模運轉的。

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?
如果我想移動這些圓磐，我先把從n-1個圓磐1,移動到多餘的柱子上去，這樣我就能把最底下的圓磐放到這兒了，然後再把從n-1個圓磐放到這兒來,這就是確切的我怎麽做的對不對？

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.
