WebIn optics, an ultrashort pulse, also known as an ultrafast event, is an electromagnetic pulse whose time duration is of the order of a picosecond (10 −12 second) or less. Such pulses have a broadband optical spectrum, and can be created by mode-locked oscillators. WebA low-repetition-rate oscillator that generates pulses with large and linear chirp can replace the standard oscillator, stretcher, pulse-picker, and preamplifier in a chirped-pulse fiber amplifier. The theoretical properties of such a giant-chirp oscillator are presented.

The output optical signal has a positive chirp after passing through the PM, then a 290 m single-mode fiber is set for chirp elimination to perform ultra-short pulses … WebAbstract. We demonstrate a pre-chirp managed Yb-doped fiber laser system that outputs 75 MHz, 130 W spectrally broadened pulses, which are compressed by a diffraction-grating pair to 60 fs with average powers as high as 100 W. Fine tuning the pulse chirp prior to amplification leads to high-quality compressed pulses.

WebDec 1, 1985 · We have demonstrated the amplification and subsequent recompression of optical chirped pulses. A system which produces 1.06 μm laser pulses with pulse widths of 2 ps and energies at the millijoule level is presented. WebAccurate simulation of scalar optical diffraction requires consideration of the sampling requirement for the phase chirp function that appears in the Fresnel diffraction expression. We describe three sampling regimes for FFT-based propagation approaches: ideally sampled, oversampled, and undersampled.

WebWhen the CS-DSB optical signal is detected by a photodetector (PD) at a base station (BS), the dual-chirp waveform is generated. However, along with the transmission to different BSs before emission, the chromatic dispersion of fiber will cause power fading.
