Direct fabrication of arbitrary phase masks in optical glass via ultra-short pulsed laser writing of refractive index modifications

HIGHLIGHTS

• who: A. Schu00fcller-Ruhl from the FH Aachen, University of Applied Sciences, Aachen, Germany have published the paper: Direct fabrication of arbitrary phase masks in optical glass via ultra-short pulsed laser writing of refractive index modifications, in the Journal: (JOURNAL)
• what: With several proof-of-principle examples the authors show the feasibility of the method . In the following parameter study, the authors determine the most suitable parameters to create a refractive index modification with a stable and preferably small size. In Fig 1 the authors show the refractive index modifications created with 1000 pulses . . .
