Abstract

Non-degenerate two-wave mixing in inverted laser materials is investigated both theoretically and experimentally. A complete model of two-wave mixing in gain media in the presence of an athermal refractive index grating is presented and application to beam-combining is investigated in pumped ${\text{Nd}}^{3+}$ and ${\text{Yb}}^{3+}$ laser materials. Experimental results are presented for a Nd:yttrium aluminum garnet crystal fiber.
