Abstract
The paper presents the result of investigations of spectroscopic parameters of YAG:Cr4+ crystals. The non- saturable component of the absorption coefficient, absorption cross-section, active centers concentration, excited state lifetime and energy consumed for bleaching effect have been estimated. Investigations of YAG:Cr4+ spectroscopic properties, and measurements of absorption and luminescence bands, allow the estimation of chromium ion concentration at particular charging state and positions in YAG crystalline structure, and allow also to determine their mutual relations and influence of these relations on the non-linear properties of absorber.
