Abstract
The stimulated Raman-scattering (SRS) gain coefficient has been measured qu antitatively for the first time to our knowledge in Yb:Sr-5(PO4)(3)F to be 1.23 +/- 0.12 cm/GW at 1053 nm. These data, along with surface and bulk los ses, feedback that is due to surface reflections, gain saturation, and band width, have been applied to a quantitative model that predicts the effects of SRS within a laser amplifier system where the laser gain media show SRS gain. Limitations and impact to the laser amplifier performance are discuss ed, along with possible techniques to reduce SRS loss. (C) 2000 Optical Soc iety of America.
