Compared with a sech2-shaped pulse, a Gaussian pulse with the same width at half-maximum has somewhat weaker wings:Figure 1: Temporal shapes of Gaussian and sech2 pulses.The peak power of a Gaussian pulse is ≈ 0.94 times the pulse energy divided by the FWHM pulse duration....
By detuning the center frequency of the dispersion broadened pulse from the resonant frequency of the grating, a combi 我们认为40ps全宽在半最大(FWHM)高斯脉冲在1.55 m波长,唧啾叫由传播通过纤维的100公里长度,是事件在一致的Bragg滤栅。 通过解谐分散作用的中心频率扩展了脉冲从滤栅,刺耳导致的分散作用的...
The output spectrum is close to the Gaussian profile with a full-width half-maximum (FWHM) output of 49nm, and the measured autocorrelation trace exhibits the Gaussian profile. The shortest pulse duration of 70 fs was observed after external recompression. The time-band product is 0.44, showing...
Know how to generate a gaussian pulse, compute its Fourier Transform using FFT and power spectral density (PSD) in Matlab & Python.
An estimate of conversion efficient at arbitrary levels of depletion ηest is obtained with the empirical expression: [45]ηest=ηcalc/1+ηcalc Returning to the example 1.064 nm to 532 nm, type-II SHG in KDP and using l=3cm, Uω0=0.3J, and τ=3.6ns for a 6 ns FWHM pulse ...
PULSELENGTH: The full-width at half-maximum (FWHM) power temporal duration of the pulse. OFFSET: The time at which the source reaches its peak amplitude, measured relative to the start of the simulation. An offset of N seconds corresponds to a source which reaches its peak amplitude N sec...
We assume an incident pulse with a central wavelength of 800 nm, a pulse duration (FWHM) of 60 fs, and a beam waist (FWHM) of 1 cm. Accordingly, the nonlinear refractive index in air is 𝑛2=0.5×10−19cm2/Wn2=0.5×10−19cm2/W and the astigmatic coefficient is 𝐶6=0.005...
If I have a pulsed laser with 10 μJ pulse energy and the beam is Gaussian, is that energy the average energy or the peak energy? Would the energy at tip of the distribution (the center of the beam) be equal to 10 μJ or less by a factor? The author's answer: Pulse energy is...
