WebAug 8, 2024 · Abstract: The build-up of a self-started stretched-pulse fiber laser was experimentally investigated using time-stretched dispersive Fourier transform spectroscopy. Interestingly, soliton pulsations were observed in a rich set of clustered Q-switching bunches in the turbulent and rapidly-evolving pre-mode-locking states of the laser.

WebSep 22, 2024 · Start by configuring the counter to measure *periods* between consecutive photon pulses. Once you have the individual periods, you can easily make a timestamp by performing a cumulative sum. Below is a LV 2013 snippet to illustrate how to get started. I set the default value of the signal whose period to measure to be an internal 100 kHz clock.
WebTime stretching is the process of changing the speed or duration of an audio signal without affecting its pitch. Pitch scaling is the opposite: the process of changing the pitch without affecting the speed.Pitch shift is pitch scaling implemented in an effects unit and intended for live performance. Pitch control is a simpler process which affects pitch and speed … be650g1 manualWebNov 20, 2014 · We derived the STSP by extending a time-stretched pulse (TSP) to the spatial domain; therefore, an STSP is a signal whose temporal and spatial frequencies … desert jojoba oilWebAug 12, 2016 · At the heart of time-stretch imaging is its all-optical encoding of image frames in the individual laser pulses in real time, at a frame rate defined by the repetition rate of the ultrafast pulsed ... be65t-h manualWebIndeed, most of the time, DFT is achieved through an optical fiber in which the ultrashort pulses temporally stretch by a factor of more than a million.
