Design and Analysis of the Parameters of Anend Pumped Nd:YVO4 Laser at Near Infrared Electromagnetic Spectrum

This research presents the design and analysis of a solid-state laser tailing based on an Nd:YVO4 diode. Simulations predict a 43% optical-to-optical conversion efficiency, generating 25W of power at 1064nm with a 50W pumping power. Using LASCAD software, the analysis confirms the accuracy of the calculations for extractable power and laser intensifier stability. Additionally, COMSOL physical analysis software simulates the temperature of the laser crystal under optical pumping, indicating a maximum temperature increase of 300K at the crystal center. Our findings closely match the simulations conducted using Abaqus mechanical analysis software. The peak thermal stress, approximately 25 MPa, reaches only 50% of the Nd:YVO4 crystal's tolerable limit. This lies well within the safe operating range for optical pumping, ensuring the active material remains intact.
