摘要
Tm-doped 790-nm-pumped silica fiber lasers are excellent candidates for producing emission at < 1.95 mu m, but achieving efficient operation at these wavelengths requires careful attention to fiber design because of the characteristic three-level reabsorption effects. We present a discussion of methods for mitigation of these effects and two high-efficiency systems that are capable of producing up to 70 W at < 1.92 mu m. (C) 2009 Optical Society of America
