Measurements of photoinduced light absorption in Ca₃Mn₂Ge₃O₁₂ revealed some unusual features: a saturation with the pumping intensity and a broad straggling of relaxation times with a predominance of very long times. These experimental facts cannot be understood in terms of photoinduced absorption c...
