Imaging with Diffractive Axicons Rapidly Milled on Sapphire by Femtosecond Laser Ablation
Daniel Smith, Soon Hock Ng, Molong Han +4
Fabrication of large area (sub 1 cm cross-section) micro-optical components in a short period of time (approximately 10 min) and with lesser number of processing steps is highly de…
All femtosecond optical pump and X-ray probe: holey-axicon for free electron laser
V. Anand, J. Maksimovic, T. Katkus +21
We put forward a co-axial pump(optical)-probe(X-rays) experimental concept and show performance of the optical component. A Bessel beam generator with a central 100 micrometers-dia…
Fresnel incoherent correlation holography with single camera shot
Vijayakumar Anand, Tomas Katkus, Stefan Lundgaard +4
Fresnel incoherent correlation holography (FINCH) is a self-interference based super-resolution three-dimensional imaging technique. FINCH in inline configuration requires an activ…
Dielectric cross-shaped resonator based metasurface for vortex beam generation in Mid-IR and THz wavelengths
Raghu Dharmavarapu, Ken-ichi Izumi, Ikufumi Katayama +7
Metasurfaces are engineered thin surfaces comprising two dimensional (2D) arrays of sub-wavelength spaced and sub-wavelength sized resonators. Metasurfaces can locally manipulate t…
