AI-generated deep summary
This Research Square preprint proposes enhanced temporal self-compression of laser pulses in plasmas using nonlinear pump–probe interaction, but the provided content contains no experimental details, results, or conclusions because the authors withdrew the full text after it was posted without full consent of all authors. The only substantive information available is the withdrawal/editorial note stating the paper should not be cited as a reference, alongside declarations that report no competing interests and that the work is not peer reviewed. The major limitation explicitly reflected in the record is the lack of accessible full text, preventing assessment of methods or findings. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract
Abstract The generation of ultrashort, high-intensity laser pulses are critical for frontier research across physics and materials science, yet achieving high efficiency and control remains a challenge. Here, we computationally demonstrate a novel method for ultra-efficient self-compression of a high-intensity laser pulse within a plasma, exploiting the medium's unique relativistic nonlinearities and group velocity dispersion (GVD). Our simulations show that a co-propagating, low-intensity probe beam with a super-Gaussian profile synergistically enhances the nonlinear interaction. This cooperative effect drives an increased energy loss at the trailing edge of the pulse, leading to amplified self-phase modulation and a dramatic spectral broadening. Unlike solid-state media, plasma exhibits an anti-solid state GVD, which naturally compensates for the spectral chirp induced by the nonlinearity, ultimately leading to significant self-compression. This approach achieved a pulse compression from 100 femtoseconds to an unprecedented 19.06 femtoseconds. This work presents a robust, all-optical technique for generating ultrashort pulses, with potential for more compact and powerful laser systems.
