Geometry in real space of an asymmetric Bragg case (a) and Laue case (b) diffraction. Here K0 and Kh are the average wavevectors of the incident and reflected pulses, respectively; N is the normal to the long axis of the reflected pulse; (xs, zs) is a Cartesian system of coordinates on the source surface, (x, z) is a system of coordinates on the crystal surface, the system of coordinates (xh, zh) moves together with the reflected pulse, axis zh is directed along the wavevector Kh; axes of the moving system of coordinates (xp, zp) are directed along the main axes of the pulse, φh is an angle between the normal N to the reflected pulse and the direction of pulse propagation Kh. |
