Abstract: Network, in particular a wireless network according to IEEE standard 802.11 or the like, wherein the network comprises of an arbitrary number of access points and a multitude of preferably mobile client stations is—regarding a functionally reliable organization process of the network, that in particular scales also for larger networks—designed and further developed with easy means in such a way that the access points communicate with each other and auto-configure themselves in a decentralized manner by exchanging information.

Abstract: An excimer master-oscillator-power amplifier (MOPA) system includes two laser discharge units (LDUs). Optical modules are associated the LDUs for forming the master oscillator and the power amplifier. The discharge units are each assembled onto a chassis via a vibration-damping suspension. The optical modules are assembled on a frame that is separately attached to the chassis. Providing the separate frame for optical modules, mechanically isolated from the LDUs because of the vibration isolating suspension, minimizes transmission of vibrations from the LDUs to the optics modules.

Abstract: A ventilation system for industrial laser systems is disclosed which can minimize the cooling air intake required during normal operation. Adequate ventilation is maintained even if the housing is opened. Various sensors monitor the condition of the cooling air and can increase the air intake if required for cooling or safety. Such a ventilation system is of particular advantage for exciter lasers in microlithography applications because the consumption of conditioned clean room air is controlled by the actual needs of the laser device.
