Presented at ICALEO 2012

Brazilian industrialization started to be significant after World War II. Governmental decisions to put the transport on roads and away from the rails turned on the need to build Brazilian cars, trucks and busses and new roads crossed the country.
Universities were designed to be higher education schools. Research was written in small letters and in the natural sciences area mainly were supported basic researches, as in physics. There was no model availabl...

Presented at ICALEO 2012

Innovation and invention are the hallmark of the American economy and enables ideas to flourish from humble origin to global marketplace. A combination of ingenuity, infrastructure and investment (I3) created a technology transfer ecosystem, which produced many a success story surpassing all other economies in the world. This paper describes the journey of photon from a laboratory to a factory floor, both for manufacturing and measurement with two different paths.

Presented at ICALEO 2012

A compact, all passive optical design laser beam analyzer has been developed which can analyze a focused laser beam from a CO2 laser with a wavelength range of 9.4 microns to 10.6 microns and provide real time M-squared, spot size, astigmatism, beam divergence, Rayleigh length and focal position values. The instrument utilizes a special Fabry-Perot resonator and a bolometer sensor which provides a complete beam waist caustic in real time. The unique optical d...

Presented at ICALEO 2012

Though the genesis of the disk laser concept dates to the early 90’s, the disk laser continues to demonstrate the flexibility and the certain future of a breakthrough technology. On-going increases in power per disk, and improvements in beam quality and efficiency continue to validate the genius of the disk laser concept. As of today, the disk principle has not reached any fundamental limits regarding output power per disk or bea...
