- In the present work we provide an analysis of the accuracy of the calculation of Cr4+ concentration in Cr4+:YAG using absorption spectroscopy. We propose a new approach based on the convenient optical spectroscopy to estimate the Cr4+ concentration in Cr:YAG using survey absorption spectra. The Smakula Dexter formula is usually used for this purpose. However, the uncertainties in the values of oscillator strengths for Cr4+ absorption bands and, moreover, in the deconvolution of Cr4+ absorption spectra make it difficult to calculate the Cr4+ concentrations with high accuracy.
