Predicting ablation-assisted nanosecond laser fabrication of glass optical diffusers by machine learning by Ryoma Kawaoto, Tomotaro Namba, Yukiyoshi Ohtsuki, Feng Yan, Takashi Nakajima

“…Therefore, the present ML models need to address these two different types of interactions. Through the proof-of-concept demonstration in the present case study, we show that fully connected neural network models, trained with a relatively small number of experimentally measured data, can reasonably predict the properties of glass optical diffusers fabricated by indirect laser machining. …”
