We present a machine learning approach to program the light phase modulation function of an innovative thermo-optically addressed, liquid-crystal based, spatial light modulator (TOA-SLM). The designed neural network is trained with a little amount of experimental data and is enabled to efficiently generate prescribed low-order spatial phase distortions. These results demonstrate the potential of neural network-driven TOA-SLM technology for ultrabroadband and large aperture phase modulation, from adaptive optics to ultrafast pulse shaping.

- - The study explores the laser-induced damage threshold (LIDT) of various nematic liquid crystal mixtures using femtosecond laser pulses, with a focus on real-time monitoring through spectral-domain interferometry.
- - Different laser pulse durations (from 180 fs to 1.8 ps) and repetition rates (up to 1 MHz) reveal that the LIDT is influenced by ionization at lower rates and linear absorption at higher rates.
- - The research finds that LIDTs exceeding 1 for all three liquid crystal mixtures (MLC2073, MLC2132, and E7), and also examines the LIDT of polyvinyl alcohol using the same techniques.
