1. A method for preconditioning a lithium niobate or lithium tantalate crystal, the method comprising:

  • covering at least a portion of a surface of the crystal with a condensed material including one or more active chemicals;

    heating the crystal in a non-oxidizing environment above an activating temperature at which the active chemicals contribute to reducing the crystal beneath the covered surface portion; and

    cooling the crystal from above the activating temperature to below a quenching temperature at which the active chemicals become essentially inactive for reducing the crystal.
