WebWe report a 589-nm laser using the sum-frequency generation (SFG) of 1.158- and 1.197-μm Stokes Raman lasers. These Stokes lasers are based on two KGd (WO4)2 and Ba (NO3)2 external Raman laser oscillators. First, a high-energy 1064-nm source was built to pump stimulated Raman scattering. Multiorder Stokes lasers with pulse energies of 402 and ... WebSolid Ba(NO(3))(2) is gradually dissolved in a 1.0xx10^(-4)M" "Na(2)CO(3) solution.
