  Self-focused Laser Cutting

  High-power femtosecond (fs) laser pulses have been found to propagate in transparent media and even in the atmosphere as thin white-light filaments. These filaments can be attributed to nonlinear optical phenomena. They can propagate over distances of several kilometres exhibiting power intensities on the order of 5x1013 W/cm2. If the filament hits a solid target, also there a plasma is ignited. Without any need for focussing equipment, the laser beam can be used for welding or cutting processes. The spectroscopic analysis of the generated plasma is an additional application allowing determination of solid state composition of the target. We offer a new method for material processing and material analysis by laser filaments.

  Electrooptical sampling in frequency range via controlling difference of phase

  This is a method to sample an electronic component for its frequency response in a particular entire way. A pulse laser system with a controllable pulse frequency is used to detect the amount and phase relating to the fundamental frequency of an electronic signal. Thus, this system can be considered as a kind of rapid oscilloscope coupling two high frequency sources. It acts further as an advanced network analyzer measuring not only on the fundamental frequency, but also its harmonics.

  Growth controlled current-confinement for a semiconductor laser

  The resulting structure is planar, enabling ease in contacting, and the sides of the stripes are in intimate thermal contact with material which is thermally conducting, but eletrically insulating. The pre-patterned substrate made of a robust amorphous material is 10-50 nm thick. It is able to withstand the temperatures of growth and processing (up to ca. 600 °C).

  Multi-tasking GOMS for modelling

  The invention describes a simulation system and a simulation method for studying the operability of a vehicle by an operator. The method is characterized by a Primärdatensatz with a fixed predetermined resource profile for solving at least one primary task when operating the vehicle. In this way an elaborate simulation of the primary task is avoided and enables an effective linkage with a Sekundärdatensatz, which affects at least one secundary task, especially the usability of a infotainment system and / or dialogue system while operating the vehicle.

  Multi-wavelength Cavity Ring-down Spectroscopy and Cavity Ring-down Spectrography with coherent supercontinuum light sources

  This invention describes the “Supercontinuum Cavity Ring-Down Spectrography” (SCCRDS) which is an improvement of the “Cavity Ring-down Spectroscopy” (CRDS). The principle of the novel SCCRDS technique combines the coherent and spectrally broad light of Supercontinuum (SC) with the wellestablished CRDS principle. This broadband version of Cavitiy Ring-Down Spectroscopy bases on SC light generated by white light filaments in a quartz block. Contrary to existing solutions the measurement setup consists of one light source, a cavity with a simple design and a single detection unit common for all wavelengths. SCCRDS potentially offers several advantages as compared to classical CRDS, e.g., simultaneous and multiwavelength analysis of trace absorption or sensitive heterodyne detection of signals. The spectral range of SCCRDS is unprecedentedly broad, spanning the region from UV to IR. Sale
