Capacitive-mesh output couplers for optically pumped far-infrared lasers.
The use of capacitive-mesh output couplers for optically pumped far-infrared molecular lasers has been extended throughout the far-infrared spectrum, between 42 microm and 1.2 mm, and the optimum grid constants have been found for several lines. At shorter wavelengths, performance has been improved by the use of a novel hybrid capacitive-mesh hole output coupler.
متن کاملBatch-Processed Vacuum-Sealed Capacitive Pressure Sensors
This paper reports two multitransducer vacuumsealed capacitive barometric pressure sensors, one using singlelead and the other using multiple-leads to transfer the electrical signal out of the vacuum-sealed reference cavity. The first device operates with a resolution of 37 mtorr over a pressure range from 600 to 800 torr. The sensitivity is 27 fF/torr (3000 ppm/torr). The TCO at 750 torr is 39...
متن کاملAn output coupler for Bose condensed atoms
The observations of BEC have stimulated interest in atom lasers, coherent sources of atomic matter waves. The build-up of atoms in the ground state of a magnetic trap is analogous to stimulated emission into a single mode of an optical laser. An important element of a laser is an output coupler, which provides a controlled way of generating a coherent propagating beam. We demonstrated a scheme ...
متن کاملResonator with variable-reflectivity output coupler.
A novel resonator is proposed, in which the polarizing properties of standard grating and polarizing components (such as Brewster angle windows) inside the cavity are used to vary continuously the ouput coupling over a wide range of values. An analysis of the polarization properties of the modes of such a resonator is presented, and practical suggestions are made about the choice of the polariz...
متن کاملOutput Coupler for Bose-Einstein Condensed Atoms
We have demonstrated an output coupler for Bose condensed atoms in a magnetic trap. Short pulses of rf radiation were used to create Bose condensates in a superposition of trapped and untrapped hyperfine states. The fraction of out-coupled atoms was adjusted between 0% and 100% by varying the amplitude of the rf radiation. This configuration produces output pulses of coherent atoms and can be r...
