The dark traces induced by high-power laser radiation in LiNbO3:Mg and LiNbO3:Zn are found to be reduced by annealing the crystals in an O2 atmosphere. Most of the decrease of the second-harmonic generation efficiency η for 1064–532 nm conversion due to dark traces can be recovered in heat-treated crystals. The transmission loss spectra ΔT(λ) of dark traces show a complex absorption band ranging from 365 nm to near infrared, which can be decomposed into three main peaks at 3.1, 2.5, and 1.6 eV. Maximum transmission loss due to dark traces after 1200 shots with an input power density of 18 MW/cm2 is 17% and 25% for as-grown LiNbO3:Zn and LiNbO3:Mg crystals respectively, and it is reduced to 4.6% and 3.8% respectively for heat-treated crystals. © 1996 American Institute of Physics.
