The study investigates the use of probabilistic amplitude masks in producing complex phase profiles in Photo-Thermo-Refractive (PTR) glass. Conventional binary masks face limitations in achieving intricate phase distributions. A novel approach employing probabilistic masks is introduced to exploit diffraction effects during recording. Optimization studies reveal smaller pixel sizes yield better results. Practical implementation demonstrates cost-effectiveness and comparable fidelity to grayscale masks in generating optical vortices. Challenges exist in applying probabilistic masks to Fresnel lenses, requiring further research for optimization. This study opens avenues for economical alternatives in phase mask technology.
