Growth of Nd:YAG and Cr, Nd:GScGG - A comparative study
Abstract
The influence of the physical and chemical properties of YAG and GScGG on crsytal growth and laser operation is studied. The properties of these laser materials are described. The garnet crystals are grown by the Czochralski method using an iridium crucible. The effects of the segegration coefficient of Nd on the growth of YAG and the impact of the chemical decomposition of Ga2O3 on the growth of Cr, Nd:GScGG are examined. The thermal conductivity (TC) of GScGG and YAG is evaluated; the TC of GScGG is lower than that of YAG. The data reveal that the use of Cr, Nd:GScGG crystals as laser material is limited by its tendency to solarize or darken on exposure to UV radiation and an anomalous absorption band at the one micron wavelength. It is noted that the characteristics of YAG and GScGG require different growth conditions in order to produce single crystals with high optical quality.
