Improvement of Laser Beam Quality by Compensating Thermally Induced Lens in Solid-State Lasers

R. M. El-Agmy and N. Al-Hosiny

Numerical simulations for compensation of thermally induced lens in diode pumped Nd : YLF laser rod are presented. We have proposed a design for intra-cavity compensation of thermally induced lens for π-polarization. The numerical calculations showed that the Nd : YLF laser rod can be pumped up to 850 W before rod fractured. Temperature and stress distributions around pumped are in the Nd : YLF laser rod are also presented.
