Abstract

Computational study of nanosecond pulse laser radiation in periodically poled LiNbO₃ crystals reveals the complex spatio-temporal evolution of the 1.064 mum fundamental harmonic and second harmonic energy fields with associated temperature fields, leading to the thermal dephasing and inhibition of second harmonic generation.
