The growing demand of sustainable and biocompatible optical devices is stimulating the development of naturally derived biomaterials for optics and photonics. As a versatile biomaterial, silk provides excellent material characteristics that are favorable
In a certain amplification system, signal laser can be amplified from 1 nJ to 5 J. To realize a high quality imaging transfer, meet beam diameter expansion requirement, and get good filtering effects, three spatial filters are designed and assembled. Lens
