A process for providing a protection against damages in a machine head is claimed. The process comprises the following steps: First a blind steel plate (protection plate) is fixed to a protection chamber (). Then the transparent liquid jet (WJ) guided laser beam (LB) is started, which drills a transit-hole into it. This protection plate () has the transit-hole () precisely arranged on the optical axis. Therefore no further alignment is required. Further an apparatus for treating a work piece by means of a laser beam (LB) which is guided in a transparent liquid jet (WJ) is claimed. The apparatus comprises a protection chamber () mounted on the output () of a coupling unit (CU) and a protection plate () replaceable fixed to the first chamber () protecting the outlet () of the first chamber () from sputtered debris.

Method and apparatus for improving reliability of a machining process

Apparatus for demultiplexing a wavelength division multiplexed optical signal comprising a plurality of signals each having a different wavelength. The apparatus comprises a demultiplexer sub-assembly and a multi-channel receiver optical sub-assembly. The demultiplexer sub-assembly comprises a filter block sub-assembly for splitting the input optical signal. The receiver optical sub-assembly comprises an array of photo detectors for converting the optical signals from the filter block sub-assembly into electrical signals. The electrical signals are amplified by amplifier ICs and transmitted through electrical leads. The demultiplexer sub-assembly and the multi-channel receiver optical sub-assembly are actively aligned and fixed together.
