When subjected to ultrafast laser pulses, quartz glass can take on metallic properties, turning briefly from electrical insulator to conductor. A team at the Vienna University of Technology had previously demonstrated this effect, and is now studying this further using large-scale computer simulations.

Bandpass Polarizer
Meadowlark Optics
Meadowlark Optics’ new bandpass polarizer is manufactured by depositing the filter coating on fused silica. This works well in situations when the user only wants a small wavelength range to pass through with a specific polarization.

Design of Long Working Distance Graded-index Fiber Lens With a Low NA for Fiber-Optic Probe in OCT Application
OFS
A fiber-optic probe for optical coherence tomography (OCT) applications typically includes a short section of graded index (GRIN) fiber fused onto a single-mode (SM) fiber. The GRIN fiber acts as a lens to focus the output of the SM fiber and to collect the reflected light from the sample. In this paper we will use the beam propagation method (BPM) to analyze the output beam characteristics such as beam radius and working distance, and then compare these with the measured results. With this tool we can design a GRIN fiber lens to achieve a long working distance without degrading the system performance.
