We quantitatively track in real-time, the changes in domain statistics with electric field poling, of a ferroelectric Bi 4Ti 3O 12 thin film using optical second harmonic generation as a probe. The ferroelectric hysteresis loop is extracted from these optical measurements using a theoretical model. The model also yields ratios of intrinsic nonlinear coefficients such as d 11/d 12 = -3.54 ±0.31, d 26/d 11 = 0.4 ±0.03, and optical birefringence |n b - n a| = 0.079 ±0.015.
