摘要： The invention relates to a vacuum cleaner with a dirt collection tank which has a suction inlet and is in flow connection with at least one suction unit via at least one filter and at least one extraction line, and with at least one external air inlet which opens into the extraction line downstream of the at least one filter and can be closed by means of at least one closing valve, wherein the at least one closing valve has a valve member which can be moved back and forth between a closing position and an open position, wherein it is acted upon permanently by a closing spring with a closing force and in the closing position, in addition, by a magnetic holding device with a magnetic holding force. In order to develop the vacuum cleaner further in such a manner that it makes a particularly effective cleaning of the at least one filter possible, it is suggested in accordance with the invention that the magnetic holding device comprise an electromagnet with a magnetic core and a coil which can be acted upon with current for the purpose of closing the closing valve, wherein at least one electrical component, which takes up at least some of the energy stored in the coil when the current acting on the coil ceases, is connected in parallel to the coil.

摘要： The invention relates to a laser amplifier system consisting of a solid body, which comprises a laser-active medium, of a pumping radiation source for generating a pumping radiation field, which repeatedly permeates the solid body, and of a focusing system. Said focusing system generates a number of different branches of the pumping radiation field that enter the solid body and converts at least one branch emerging from the solid body into one of the branches which enter the solid body and which are different from the emerging branch. The aim of the invention is to improve a laser amplifier system of the aforementioned type in order to be able to generate the highest possible pumping power density in the solid body while requiring the smallest possible amount of complexity. To this end, the focusing system comprises at least one deviating unit which converts, by deviating the radiation field with regard to a single plane of symmetry, at least two first partial branches formed from at least two different branches of the pumping radiation field emerging from the solid into at least two corresponding second partial branches which locally extend in a manner that is separate from the first partial branches and of which at least two branches entering the solid body are formed.

摘要： In order to improve a laser amplification system, comprising a solid-state body having a laser-active medium, a pumping radiation source for generating a pumping radiation field which passes through the solid-state body several times, an optical pumping radiation imaging means which is arranged between the pumping radiation source and the solid-state body and focuses a leg of the pumping radiation field entering the solid-state body onto the solid-state body and at least one optical refocusing means which focuses a leg of the pumping radiation field exiting from the solid-state body onto the solid-state body again in the form of a leg entering the solid-state body and different to the outgoing leg, in such a manner that as high a pumping radiation power density as possible can be generated in the solid-state body with as little resources as possible it is suggested that the optical refocusing means reshape the leg exiting from the solid-state body into an intermediately collimated leg and reshape the intermediately collimated leg again into the leg entering the solid-state body again and focused onto it.
