现代科学因其量化属性而能够做到自己的本分;它依靠测量和计算来提供可靠的结果。
随着将激光越来越普遍地用作科学研究工具,需要对激光的表现进行准确而客观的测量。
例如荧光显微镜。在诸如光漂白或光活化的应用中,对所施加的功率给出精确定义,对于实验的可重复性至关重要。但是,光源的功率输出会随时间而变化;此外,传递给试件的总能量也取决于显微镜的光束路径,以及所使用的滤光片组和物镜。这样就更难以对在不同显微镜上进行的实验进行对比。在物体平面本身使用精确校准的功率计时,无论光源或显微镜的光学细节如何,都可以测量施加到试件的准确光量。 这样以来......客观测量值就能够让研究人员利用不同的光学设备和设置直接对比所进行的实验结果。

我是一名五年级研究生,在加州大学伯克利分校的Saykally小组工作。我的研究重点是利用二次谐波产生(一种表面选择性非线性光学技术)来研究空气/水界面。 阅读更多 >

Lasers used in labs must be measured. However, there are usually many constraints, even besides the obvious one (money): 阅读更多 >

To begin we would probably specify its color or, more accurately, its spectral distribution. We would also need to describe its spatial distribution, i.e. the intensity versus position in a cross section of the beam. But light, of course, is a vector phenomenon so our characterization would also need to include the direction of the electric and magnetic fields (polarization). 阅读更多 >

Whether you're a lab researcher or an industrial worker, there are several parameters you might need to calculate, such as power density or ideal focus spot size. We've recently added a few calculators to our website. I hope these calculators make your work just a little bit easier. We have five laser optics calculators (so far): 阅读更多 >
