By second harmonic generation in and out of the principal planes we estimated the three nonlinear coefficients of the Li-containing mid-IR crystals LiGaS2 and LiGaSe2 which are isostructural to LiInS 2 and LiInSe2 and possess even larger bandgaps. First results on optical parametric amplification reveal their advantages for direct down conversion to the mid-IR.
