Performance of a neodymium yttrium aluminum borate green laser pumped with a fiber-coupled laser diode

摘要

Using a space-dependent rate-equation model and considering the effect of pump beam quality, the optimum pump condition for a fiber-coupled diode end-pumped neodymium yttrium aluminum b0rate laser has been determined. Under optimum pump conditions, greater than 10% optical-to-optical conversion efficiency was obtained when the laser was pumped by a fiber-coupled laser diode with good beam quality. The influence of pump beam quality on the conversion efficiency is also discussed. # 1998 Optical Society of America OCIS codes: 140.3480, 140.5560.
