Spectrum from the initial pulse, compressed pulse in the scheme with interferometer (Figure 1a), and compressed pulse in the scheme without having interferometer (Figure 1b) for 50 fs (a,b) and 30 fs (c,d) input pulses at B = /2 (a,c) and B = 5 pulse inside the scheme without having interferometer (Figure 1b) for 50 fs (a,b) and 30 fs (c,d) input pulses at B = /2 (a,c) and B (b,d). Horizontal axes are normalized for the input pulse bandwidth. = five (b,d). Horizontal axes are normalized for the input pulse bandwidth.The spectra for 50 fs and 30 fs input pulses are extremely comparable (note that the horizontal axes are normalized to the input pulse Saracatinib Data Sheet bandwidths eight.82 1012 Hz and 1.47 1013 Hz for 50 fs and 30 fs, respectively). The smaller distinction in between 50 fs and 30 fs at B = five is on account of the truth that the bandwidth for 30 fs input pulse becomes comparable towards the optical frequency. four.two. Optimal Chirped Mirror Dispersion opt As mentioned above, we defined the optimal CM dispersion opt as a dispersion which maximizes compressed pulse peak energy. When CM dispersion just isn’t precisely equal to opt , the compressed pulse power is smaller. We calculated opt as a function of B . The outcomes are shown in Figure 3, from which it is seen that correcting the quadratic spectral phase element for greater values of the B-integral necessitates a reduce (in modulus) chirped mirror dispersion opt . Furthermore, it really is clear from Figure 3 that opt is smaller sized within the case with interferometer than without the need of it. The smaller sized worth of opt offers a sensible benefit, because the fabrication of CM having a larger dispersion can be a far more severe challenge. It is worth noticing that, at a higher worth of B-integral, opt is nearly independent of B . Hence, the same CM could be utilized for a B-integral within a wide selection of values, eliminating the influence of instability in the laser parameters.Photonics 2021, eight,spectral phase element for higher values on the B-integral necessitates a decrease (in modulus) chirped mirror dispersion . Moreover, it is clear from Figure 3 that is prosmaller in the case with interferometer than with no it. The smaller value of vides a practical advantage, because the fabrication of CM using a higher dispersion can be a extra severe challenge. It’s worth noticing that, at a higher worth of B-integral, is five of eight just about independent of B. Therefore, the identical CM could be utilised for a B-integral inside a wide selection of values, eliminating the effect of instability with the laser parameters.Figure three.
