Sodium formate (NaCHO 2 ) has been found to be very nearly noncritically phase matchable for type-2 frequency mixing of the Nd:YAG laser fundamental and second-harmonic radiation at room temperature. The nonlinear optical constant was determined to be d 32 (NaCHO 2 ) = (1.25 \pm 0.25) \times 10^{-9} ESU.
