Title: Method and system for suppression of stimulated Raman scattering in laser materials

Patent ·
OSTI ID:1193296

A composition of matter is provided having the general chemical formula K(H,D).sub.2P(.sup.16O.sub.x,.sup.18O.sub.y).sub.4, where x<0.998 or y>0.002, and x+y.apprxeq.1. Additionally, a method of fabricating an optical material by growth from solution is provided. The method includes providing a solution including a predetermined percentage of (H,D).sub.2.sup.16O and a predetermined percentage of (H,D).sub.2.sup.18O, providing a seed crystal, and supporting the seed crystal on a platform. The method also includes immersing the seed crystal in the solution and forming the optical material. The optical material has the general chemical formula K(H,D).sub.2P(.sup.16O.sub.x,.sup.18O.sub.y).sub.4, where x<0.998 or y>0.002, and x+y.apprxeq.1.
