Journal ArticleDOI
Ablation-cooled material removal with ultrafast bursts of pulses
Can Kerse,Hamit Kalaycioglu,Parviz Elahi,Barbaros Çetin,Denizhan Koray Kesim,Önder Akçaalan,Seydi Yavas,Mehmet Asik,B. Oktem,Heinar Hoogland,Ronald Holzwarth,Fatih Omer Ilday +11 more
TL;DR: It is demonstrated that extremely high repetition rates, which make ablation cooling possible, reduce the laser pulse energies needed for ablation and increase the efficiency of the removal process by an order of magnitude over previously used laser parameters.
Journal ArticleDOI
In-chip microstructures and photonic devices fabricated by nonlinear laser lithography deep inside silicon
Onur Tokel,Ahmet Turnali,Ghaith Makey,Parviz Elahi,T. Çolakoğlu,Emre Ergecen,Ozgun Yavuz,René Hübner,Mona Zolfaghari Borra,Ihor Pavlov,Alpan Bek,Rasit Turan,Denizhan Koray Kesim,Serhat Tozburun,Serim Ilday,F. Ömer Ilday +15 more
TL;DR: Laser-based fabrication of complex 3D structures deep inside silicon using 1-µm-sized dots and rod-like structures of adjustable length as basic building blocks are demonstrated, enabling the creation of numerous photonic devices.
Journal ArticleDOI
Breaking crosstalk limits to dynamic holography using orthogonality of high-dimensional random vectors
Ghaith Makey,Ozgun Yavuz,Denizhan Koray Kesim,Ahmet Turnali,Parviz Elahi,Serim Ilday,Onur Tokel,F. Ömer Ilday +7 more
TL;DR: F Fresnel holograms that form on-axis with full depth control without any crosstalk are demonstrated, producing large-volume, high-density, dynamic 3D projections with 1,000 image planes simultaneously, improving the state of the art for the number of simultaneously created planes by two orders of magnitude.
Journal ArticleDOI
Disorder-mediated crowd control in an active matter system
Ercag Pince,Sabareesh K. P. Velu,Agnese Callegari,Parviz Elahi,Sylvain Gigan,Giovanni Volpe,Giorgio Volpe +6 more
TL;DR: It is demonstrated that the presence of spatial disorder can alter the long-term dynamics in a colloidal active matter system, making it switch between gathering and dispersal of individuals.
Journal ArticleDOI
High-Repetition-Rate Ultrafast Fiber Lasers for Material Processing
TL;DR: In this paper, the authors provide a unified perspective of the unique opportunities created by operating at high repetition rates together with efforts into the development of enabling laser technology, including new results on further scaling up the capabilities of the laser systems.
