Design of Self-similar Pulse Compression Grating Pair based on Chirp Compensation
In order to obtain a high-quality ultrashort pulse light source, we combine the self-similar pulse with the grating pair, and analyze the evolution and compression process of the self-similar pulse in detail through a numerical simulation method. We first launch the Full Width at Half Maximum (FWHM)...

| description | In order to obtain a high-quality ultrashort pulse light source, we combine the self-similar pulse with the grating pair, and analyze the evolution and compression process of the self-similar pulse in detail through a numerical simulation method. We first launch the Full Width at Half Maximum (FWHM) of 1 ps, energy of 45 pJ Gaussian pulses into a dispersion decreasing fiber to generate the chirp self-similar pulse with strong linear characteristic. Then we use the grating self-similar pulse chirp compensation compressor to obtained an ultrashort pulse with FWHM of 80 fs and peak power of 507.6 W. The compression quality parameterQis 0.96, and the compression factor is 12.5. On this basis, we analyze the influence of the third-order dispersion in the declining fiber on the compression quality of the grating, and find that as the third-order dispersion increases, the compressed pulse quality will be significantly reduced. The results show that when the third-order dispersion effect in the system is small, high-power ultrashort pulses can be obtained by using self-similar pulses and grating pairs. This result is helpful for the acquisition of ultrashort pulses. |
