✦ Synopsis
The results of an experimental investigation of the incoherent photon echo in ruby (with Cr^3+^ concentration equal to 0.16 wt%) at T=1.7 K are presented. Optical fiber with length 3 m and diameter 100 μm was used for delivery of the first exciting pulse to a sample. The dependence of the IPE intensity on the excitation wavelength within the width of R~1~ absorption line was studied. The IPE decay curve was obtained and the phase relaxation time was found to be equal to 98 ns.
