Photonics Spectra - October 2016

…interferometric metrology tools have become necessary
for today's modern optical fabrication. The
development of digital phase-shifting interferometry in around 1970 at Bell Labs was a
crucial innovation for optical fabrication.
Without this technology, the high-precision

Mephisto Gravitational Waves 2016.pdf

…terms of low output noise and ultra-narrow linewidth requirements, few would argue that gravitational wave detection (GWD) based on long path interferometry currently represents the most demanding application for narrow linewidth CW lasers - even more than atom cooling. Successful first detection of…

Laser Focus World - June 2017

…sensitive bimetallic optics, Coherent polishes aluminum in a multi-step process. Single-point diamond turning (SPDT) is followed by Fizeau interferometry and/or a phasemeasuring microscope test to program a robotic system for "deterministic polishing." That is, variable dwell times are programmed…

…such a huge range of the
electromagnetic spectrum. Huber's group confirmed
this CEP stability by performing a standard f-2f
interferometry comparison by frequency doubling e.g.
the 6th harmonic and detecting the interference
between this and the 12th harmonic. This revealed…

…is validated and
optimized in the test lab long before they are tested in
an ultrafast laser prototype. For example, laser
interferometry is used to detect angular movements as
small as 5 micro-radians. These measurements are
made before and after subjecting the components…

…offer highly
personalized treatments such as socalled Wavefront LASIK. Here, the eye's
optical properties are fully assessed using interferometry. The surgeon then
applies a spatially varying correction
across the cornea with the goal of delivering a more optically perfect eye.…
