Hackers from all over Europe descended upon Rome last weekend for the Maker Faire that calls itself the “European Edition”. This three-day event is one of the largest Maker Faires in the world — they ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. Lasers have served as teaching tools ...

Exclusive to optics.org: Innovative intra-cavity design has produced a continuous-wave ruby laser, with other novel sources set to follow. A new source developed by Germany-based laser supplier ...

Abstract: An analysis is performed for a pulsed ruby laser with a modulator internal to the interferometer resonator. The problem is a transient one, since steady state is not reached during the ...

[youtube=https://www.youtube.com/watch?v=ZUevWmUViJM&w=580] We were again pleased to find another person who attended Maker Faire just to show off the awesome and not ...

Abstract: The frequency separation between transverse modes of a ruby laser is measured using a Fabry-Perot interferometer and a high-speed camera. The results are compared with the theoretical ...

IN a cavity laser system, oscillation by stimulated emission occurs when the gain is sufficient to overcome the total loss in the cavity. Cavity loss not only determines the threshold condition of ...
