THE commercial availability of gas-phase lasers giving a continuous output in the visible region of the spectrum solves a problem that has been troubling users of optical diffractometers for some time ...
Abstract: For refractive index measurement, this paper presents a new method based on a laser diffractometer, in which a reflective diffraction beam coincides with an incident beam. Calculation by ...
