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…

Tilted black-Si: ~0.45 form-birefringence from sub-wavelength needles
Darius Gailevicius, Meguya Ryu, Reo Honda +14
The self-organised conical needles produced by plasma etching of silicon (Si), known as black silicon (b-Si), create a form-birefringent surface texture when etching of Si orientat…

Releasable micro-waveplates
L. Grineviciute, T. Tolenis, M. Ryu +7
A simple procedure is demonstrated for fabrication of waveplates which can be released from substrate by laser cutting. Oblique angle deposition, chemical etching and laser inscrip…
