  • Diffraction of slow neutrons by nanoparticle-polymer composite gratings has been observed. By carefully choosing grating parameters such as grating thickness and spacing, a three-port beam splitter operation for slow neutrons - splitting the incident neutron intensity equally into the {+-}1st and the 0th diffraction orders - has been realized. As a possible application, a Zernike three-path interferometer is briefly discussed.
  • A new setup of interferometers is proposed in which the set of specific optical markers - optical vortices - could be generated. The classical Mach-Zender two-beam interferometer has been modernized using the Wollaston prism. In this setup, the optical vortices could be obtained for a wide range of both beam parameters. The numerical analysis and experiments confirm our theoretical predictions.
  • In this paper, we calculate optimal prism configurations for achromatic N-prism beam expanders of a single material; we argue that for moderate to high magnifications, that is M> or approx. =(2-1/(2/sup N/-1-1))/sup N/, the up-up . . . up--down configuration is generally optimal, in the sense that it maximizes the transmission for given magnification. We also derive exact expressions for the incidence and apex angles that optimize a nonachromatic N-prism beam expander of arbitrary materials. The use of simple three-prism (up--up--down) and four-prism (up--up--up--down) single-material achromatic beam expanders is suggested for applications requiring compactness, achromaticity, and temperature stability.
  • A new type of planar electro-optic prism array is presented. The array is composed of an individual pair of prisms that gives a sawtooth phase shift to the wave front of the transmitted optical beam; thus the array acts as a triangular phase grating. Theoretical analysis as well as experimental work show that the array behaves as a beam splitter. The splitting of the beam is voltage controllable.
  • A double-Wollaston prism laser differential interferometer (LDI) has been developed to observe, for the first time, the evolution of the imploding current sheath (CS) and the high temperature and high density plasma pinch in the plasma focus. The light source is a Q-switched and frequency-doubled YAG laser operated in a single-pulse mode: {lambda}=532 nm, the pulse width (FWHM) about 10 nm (also the resolution time of the LDI). The LDI measures density gradients and has a line sensitivity of about n{sub e}{sup {prime}}=(2.58{plus_minus}0.46){times}10{sup 25} m{sup {minus}4} for a typical sheath thickness of 1.6 mm and a minimum distinguishable fringe shiftmore » of 5{percent}, and a spatial resolution of 1.26 mm. The density gradient and equivalent density of the CS are measured to be n{sub e}{sup {prime}}{approx}(2.58{plus_minus}0.46){times}10{sup 26} m{sup {minus}4} and n{sub e}{approx}(3.25{plus_minus}0.59){times}10{sup 23} m{sup {minus}3}, respectively. More importantly in this article, the double-Wollaston prism LDI, with a simple optical arrangement, gives direct physical pictures of the high density gradient plasma configuration and structure which are of interest in studying the status of plasma motion. {copyright} {ital 1997 American Institute of Physics.}« less
