The invention represents the design and apparatus for a temperature-independent laser source. By isolating naturally temperature-independent wavelengths of broad band lasers with a cavity Bragg mirror, the invention herein may produce temperature stable laser output from many laser systems
The invention of the laser has enabled, and in some cases defined, most technological advancements in the last fifty years. Lasers are everywhere today and now as an established science they take many shapes, sizes, and output many wavelengths (colors), but they all share a detrimental dependence on temperature. The figure of merit associated with most lasers is, in fact, the stability of their output, which is frequently determined by fluctuations in wavelength due to temperature changes. In order to achieve the highest power output, broad band lasers are generally operated at their peak output wavelength which, unfortunately, tends to vary wildly with temperature.
Researchers at UCF have created a new laser source while focusing on laser stability, thereby solving this temperature dilemma by looking at whole output spectra. They have done so by realizing that while not offering the highest output, there exist wavelengths that exhibit little to no temperature variance. The invention herein refines this discovery by means of isolating the temperature-independent wavelengths of a system resulting in an extremely stable laser source.
