Abstract :
The optimum pump condition for a fiber-coupled diode end-pumped Nd:YAl/sub 3/(BO/sub 3/)/sub 4/ laser has been determined by including the effect of pump beam quality into the analysis. Under the optimum pump condition, 67 mW of the green laser output corresponding to a conversion efficiency 10.3% was obtained from a self frequency-doubling NYAB crystal when pumped by a 650 mW fiber-coupled laser diode. The prospect of higher conversion efficiency is also discussed.
