Configuration Q-switching in a diode-pumped multirod variable-configuration resonator

IEEE Journal of Quantum Electronics, 1998
We report on a novel technique for Q-switching at high repetition rates, where the change in the Q of the cavity is due to the capability of a variable-configuration multirod resonator (VCR) to switch between an unstable Fabry-Perot configuration and a stable ring configuration.

Mutually Pumped Phase-Conjugate Mirror: Sickle Configuration

Chinese Physics Letters, 1996
A mutually pumped phase conjugator is demonstrated with a novel photorefractive crystal of copper-doped potassium sodium strontium barium niobate, in which the beams travel in a geometric path similar to the outline of a sickle. The maximum reflectivity is up to 168%.

Novel pump configuration for thin disk lasers

SPIE Proceedings, 2005
Since its introduction the thin disk laser based on Yb:YAG material has been thoroughly investigated and first industrial systems are now available. Nevertheless, some problems arise when scaling the power up: The pump set-up is becoming complicated and there could be some difficulties in bonding the thin disk on the cooling finger. In this paper, we

Novel systems for configurable AC electroosmotic pumping

Microfluidics and Nanofluidics, 2007
In this paper we present a novel method of creating and using geometric asymmetries for AC electroosmotic pumping. The method relies on grouping similar electrodes together in terms of applied voltage, in order to create configurable asymmetries in periodic electrode arrays, which induce a net pumping AC electroosmotic velocity. Using a numerical model

Field Configurations in Electrostatic Quadrupole Pumping Structures†

Journal of Electronics and Control, 1964
Abstract The effectiveness of the potential applied to the electrodes of an electrostatic quadrupole pumping structure depends on the shape of the electrodes and on the transverse position of the electron beam. The magnitudes of these effects are calculated for commonly used structures, and appropriate electrode profiles ...

LOW THRESHOLD ELECTRON BEAM PUMPED CdS LASERS WITH END-PUMPED CONFIGURATION

Applied Physics Letters, 1970
End-pumped lasing of thin CdS crystals is reported for electron energies down to 5 kV at 77°K and 9 kV at room temperature as a result of special treatment of the Fabry-Perot mirrors. These mirrors consisted of 500 Å of aluminum on the bombarded side and a multi-layer dichroic reflector on the opposite side.
