Scientists from the University of Rochester and UC Santa Barbara have built a laser so small it can sit on a penny. But don’t ...

[John Crombie] had a crack at building one using linear Hall effect sensors and magnets as the ... [John] utilises the Arduino pro micro for its copious analog inputs and USB functionality.

Abstract: The fabrication, characterization, and gas sensor application of a hollow core photonic bandgap fiber (HC-PBGF) with laser drilled lateral microchannels will be described. The HC-PBGF was ...

Abstract: A method has been developed for measuring the width of the lock-in zone in laser gyroscopic sensors by nonlinear distortions of the scale factor that occur when the sensor rotates with an ...
