Photosensitivity of infrared glasses under femtosecond laser direct writing for mid-ir applications

HIGHLIGHTS

• who: Pierre Delullier and colleagues from the ONERA, The French Aerospace Lab, Palaiseau, France have published the research work: Photosensitivity of Infrared Glasses under Femtosecond Laser Direct Writing for mid-IR Applications, in the Journal: (JOURNAL)
• what: To open the door to the fast prototyping of complex 3D optics (geometric phase lens, gradient index optics, etc.) for infrared applications, the study seeks to understand the modifications implemented in a set of well-chosen glasses as a function of the writing parameters (laser pulse duration, pulse energy, writing speed, etc.). The authors compare the main optical . . .
