Abstract

Large third-order optical nonlinearities were studied in thin films of BiMnO ₃ (BMO) grown on SrTiO ₃ (STO) substrates by pulsed laser deposition (PLD). A single-beam Z-scan technique was employed for nonlinear fraction, and nonlinear absorption measurements at room temperature. The film response under external electric fields was probed and the Z-scan signal was measured to further probe the optical nonlinearity. The results show that the second harmonic generation (SHG) signal strength shows time dependence when subjected to a periodic wave form, resulting in different amounts of enhancement.
