The regularities of the two-pulse photon echo generation in doped crystals under changes in the angle a between directions of propagation of pumping pulses are investigated theoretically. The explanation of some experimental results obtained by U.P. Wild and coworkers, in particular, the modulation character of the response-intensity dependence on the angle a is presented.
