Performance Analysis of Laser Diode Single-End-Pumped Solid State Laser


In this work, results are presented for a continuous wave diode laser single-end-pumped Nd:YVO4 laser with maximum output power of 240mW in the TEM00 mode at an optical pump power of 850mW. The laser performance under different output couplers has been studied both analytically and experimentally. The theoretical analysis provides a good prediction of the laser performance parameters which are in broad agreement with the experimentally observed results. An optical to optical conversion efficiency of 28% and an average optical slope efficiency of 29% were obtained. The fluctuation of the output power is less than 1.5% in 10 min.
