Resumen:
Un instituto de investigación alemán ha desarrollado un nuevo concepto de espejo para resonadores Fabry-Perot que ofrece una mayor estabilidad de frecuencia del resonador con menos esfuerzo para la estabilización de temperatura. Los resonadores Fabry-Perot se emplean para estabilizar sistemas láser. El componente combina un nuevo diseño y material que permite la estabilización de frecuencia relativa en el rango de 10^(-16). Su fabricación es sencilla y rentable. El nuevo elemento combina una estabilidad longitudinal extremadamente alta a una temperatura aproximada de 20 ºC con bajo ruido térmico. El instituto de investigación busca licenciatarios.

License for mirror component for ultra-stable resonators
Summary:
A German research institute has developed a novel mirror concept for fabry-perot resonators which leads to a higher frequency stabilization of the resonator with less effort for the temperature stabilization. Fabry-perot resonators are used to stabilize laser systems. The research institute is looking for licensees.
Description:
A German research institute is searching for licensees for a mirror component for ultra-stable resonators. The component has a combination of a new design and material selection leading to a relative frequency stabilisation in the range of 10^(-16). The mirror component can be manufactured easily and cost-efficiently. The new mirror element combines extremely high length stability at about 20°C with low thermal noise. State of the art mirrors as well as the used spacers of ultra-stable fabry-perot resonators are made of ultra low-expansion glass (ULE), which has a zero finish in its length output at about 20 °C. The newly developed solution consist of a ring of ULE glass attached to the back of a quartz glass mirror. This counteracts the deformation of the mirror and the zero passage of the length expansion of the resonator is back to 20 °C. This allows fabry-perot resonators, which can be operated at room temperature and still have a much smaller thermal noise.

The novel mirror can be inserted into fabry-perot resonators, which are used to stabilize laser systems. Such laser systems achieve a relative frequency stability of up to 10^(-16). Frequency-stable lasers are used for realization of optical clocks, in communication technology to transmit ultra-stable frequencies and in the field of ultra-precision spectroscopy. The research institute is searching for licensees.
Advantages and Innovations:
The offered system offers several advantages compared with state of the art solutions:
- Use of mirror materials with lower thermal noise
- Compensation of mirror deformation caused by temperature fluctuations
- Relative length stability of 10^(-16) possible
- Cost-effective temperature stabilization up to 20 °C
