Abstract

A nondestructive method for measurements of Nd3+ concentration in Nd:YLF laser rodes is presented. The method, based on the comparison of the intensities of Nd3+ luminescence lines to the intensities of the host matrix (LiYF4) Raman lines, requires the use of a micro-Raman spectrometer. The experimental conditions have been optimized and are described in detail. The investigations were performed in the concentration range 0at.% −2at.% of Nd and the calibration curve is presented. In standard use, the relative error on the results never exceeds 10%. Using this method to study the concentration gradient in a crystal is shown and the distribution coefficient of Nd3+ in LiYF4 is deduced.
