Continuous-wave optical parametric oscillator tuned by a diffraction grating

Modal theory of diffraction : a powerful tool for the study of grating couplers in nonlinear

This « short period effect » looks like the blaze effect for the classical gratings, but, the blazing parameter is the grating period instead of the blazing angle as for the

Diffraction of a 633nm laser beam on the monoatomic steps of a vicinal (0001) sapphire surface has been observed, revealing the presence of relatively regular terraces on both

In this paper we discuss and compare these two kinds of boundary conditions again and we present some further results of the numerical calculations of

In a study of the nature and distribution of Burgers vectors of dislocations with both edge and screw components in a low angle boundary in Al 2 O 3 , having mainly a tilt

to the n~~ order Bessel function, whose argument is itself proportional to the amplitude of the ultrasonic wave and to the width of the liquid vessel.. In this letter we extend,

variation of shielding at the solid-vacuum boundary. In grazing incidence scattering experiments or for ion collisions in gaseous targets the full symmetry is lowered by selection

The basic principles of the method have already been developped elsewhere in this issue /1/ as well as the mechanisms involved in the acoustic wave generation / 2 /. We
