Material that changes transparency when lased from side?

Click For Summary
The discussion revolves around the search for materials that change transparency when illuminated by a laser from the side. Participants note that existing research primarily focuses on techniques rather than specific materials. One contributor highlights that the original inquiry lacked detail, suggesting that a more specific description of desired characteristics could yield better results. The conversation emphasizes the importance of clarity in scientific inquiries to facilitate more effective responses. Overall, the thread illustrates the challenges of finding specific photonic materials and the need for precise communication in research discussions.

I am into photonics research, and have been searching about this topic in vain, but almost nothing from Google shows up. So i turned here for some light.

Do you guys know any material that changes its transparency when a laser (or light) illuminates from its side?

i have been encountering that, but it isn't a material, it is more of a technique.

"illuminates from one side" is a "technique", no?

If you do not fully explain what you are looking for, especially specific characteristics of what you are looking for, then this is what you will get. If you look at JUST at what you asked in the first post, what I posted fit perfectly. So maybe you need to be a bit more elaborate in what you are seeking for.

Thread 'Time rondeau crystals, experimental observations'

A relative asked me about the following article: Experimental observation of a time rondeau crystal https://www.nature.com/articles/s41567-025-03028-y I pointed my relative to following article: Scientists Discovered a Time Crystal That Reveals a New Way to Order Time https://www.yahoo.com/news/articles/scientists-discovered-time-crystal-reveals-180055389.html This area is outside of my regular experience. I'm interested in radiation effects in polycrystalline material, i.e., grain...
