Abstract

We discuss the application of digital holographic monitoring for quantitative phase analysis of polarization-sensitive materials treated with femtosecond pulses. A custom-built polarization holographic microscope reconstructs the full Jones matrix with high sensitivity, operating at three wavelengths (450, 532, 660 nm) to analyze spectral anisotropy. This enables direct visualization of laser-induced phase and polarization changes, advancing controlled laser microstructuring.
