We present the possibility of effective doubling of millimeter wave radiation in the range of 400-2500 μm in borate crystals. The phase matching angles are calculated. It is shown that for LN and β-BBO crystals the realization of o + o → e and e + o → e interactions is possible, and for LB4 only o + o → e. The walk-off angle, spectral and angular phase-matching bandwidth are calculated. An estimate is given of the maximum efficiency of SHG taking into account the measured optical damage threshold of 150 TW/cm2 for the LB4 crystal and 100 TW/cm2 for β-BBO.
