Abstract:The thermal effect on the output characteristics was analyzed in an end-pumped Ho:YLF laser by applying the Kirchhoff integral analytic solution and finite element analysis using LASCAD software. At a Tm:fiber laser power of 70 W, the maximum temperature of a Ho:YLF crystal with 8 mm diameter was found to be 297.6 K. The temperature distribution results of the two calculation methods were matched with an acceptable error. The calculated thermal lens focal length for the maximum power was −985 and −976 mm in th… Show more
