SRS- and SE-active crystal with high-order Stokes and anti-Stokes picosecond .3/ -nonlinear lasing

Steady-state .3/ -nonlinear generation in the host crystal LaGaGe2O7 for Nd 3C .Ln 3C /-lasants has been discovered. All the registered Stokes and anti-Stokes lasing sidebands are identified and attributed to its SRS-promoting phonon mode at!SRS 882 cm 1 . We have classified the studied germanate as a promising crystal for self-Raman laser converters.
