  Multi-segment all-fiber laser device for optical pulse generation

  Here we introduce a new multi-segment all-fiber laser device · that emits well-defined optical pulses and/or pulse trains of well-defined but adjustable wavelength without using any external measures such as active modulation or the introduction of a saturable absorber, · that contains several segments arranged in direction along the fiber comprising at least one active laser segment, typically two (or even more) active laser segments as well as propagation, grating, and nonlinear refraction segments, · where these segments assume a cooperative mode of operation created by new types of self-organization based on the gain-phase coupling of the segments, · where pulse shape, duration, repetition rate, and/or pulse power are adjusted or tuned by either the frequency detuning of the laser segments, the propagation time delays between the segments, the nonlinear phase changes induced by the segments, or by a combination of these parameters.

  Body-Surface-Potential-Maps by utilizing a standard ECG device

  Our new method only requires a standard 12-lead ECG device with digital data output providing almost identical results as BSPM. The only real difference is that not all channels are being read out simultaneously, i.e. the mapping is reconstructed from sequentially obtained ECG-Signals. A specific digital signal processing has been developed to synchronize sequentially recorded ECG signals. The resulting data is thus competitive to the “true” parallel BSPM.

  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).

  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.
