In an earlier Letter [Opt. Lett. 37, 2136 (2012)], a conversion efficiency was improperly given. That error is corrected here.

On p. 2138 of Ref. 1, in the 33rd line in the left hand column, the conversion efficiency should be instead of . The last sentence of the paragraph should therefore be:
“Conversion efficiency depends on the encoded information, e.g., for an Airy beam  in a 0.5 mm thick crystal, it is expected to be .”
