Title: Depolarization compensator
Inventor: MICHAILOVAS ANDREJUS
IPC: H01S3/00
Filed: 2019-03-20
Abstract: This invention relates to optical elements for spatially variable polarization control, particularly, to those for compensation of light depolarization in laser systems. The depolarization compensator comprises a micro structured polarization converter with a spatially variable birefringence. It is fabricated by inscribing sub-wavelength nanogratings in a volume of a sample by ultrafast laser radiation. Nanogratings with different orientations and retardance at various positions of the converter’s cross-sectional area are inscribed. An impact on polarization while traversing said micro structured polarization converter is such that compensates the impact on polarization the laser beam experiences while traversing a thermally loaded optical element. The depolarization compensator can be implemented in high-power laser systems. It is suitable for lasers with unstable resonator configuration. It is particularly suitable for linear single-pass or double-pass amplifiers.

Abstract: A group control for double car elevators permits the upper as well as the lower cars to be used at a main stopping floor for travel to both even-numbered and odd-numbered floors. The control has a call memory for each car in which the target calls entered at the main stopping floor and identifying the target floors are stored. A switching circuit has an input connected to the call memories in such a manner that the double car is scheduled in dependence on the allocated call as stopping at floor pairs numbered even-odd or odd-even. An output of the switching circuit is connected to a switching device which excludes either the double cars stopping at floor pairs numbered even-odd or at floor pairs numbered odd-even from the allocation process in the case of a subsequent call to be allocated in order to maximize the possiblilities for coincident stops without losing flexibility.
