Temporally And Spatially Resolved Wide-field Nonlinear Imaging - EPFL

Temporally And Spatially Resolved Wide-field Nonlinear Imaging - EPFL A new measurement technique, capable of quantifying the number and type of modes propagating in large mode area fibers is both proposed and demonstrated. the measurement is based on both spatially and spectrally resolving the image of the output of the fiber under test. Mode content is characterized using spatially and spectrally resolved (s 2) imaging, revealing a variety of phenomena. discrete mode scattering to core guided modes are measured at. In this work we present several algorithms that significantly improve the accuracy of modal reconstruction for weak excited fundamental mode content. we show that in some cases general analytical solutions exist that can completely overcome the former limitation. This method significantly reduces the requirement for precision of mobile platforms and is suitable for measuring the modal content of a high power fiber laser output beam.

This method significantly reduces the requirement for precision of mobile platforms and is suitable for measuring the modal content of a high power fiber laser output beam. We present a fast implementation of the spatial and spectral imaging (s 2) technique for modal analysis of multimode optical fibers. Higher order modes propagating in large mode area fibers are characterized using spatially and spectrally resolved modal imaging. the measurements provide the fraction of power contained. The principles of spatially and spectrally resolved (s2) imaging are extended to include spectral phase information which yields a measurement which is resolved. We refer to the measurement as spatially and spectrally resolved imaging of mode content in fibers, or more simply as s 2 imaging. (c) 2008 optical society of america.
