    "abstract": "Self-compression of femtosecond laser pulses and more than an order of\nmagnitude increase of the peak intensity is found in a positive dispersion\nmedium in low dispersion regime based on the (3+1)-dimensional nonlinear\nSchr{\\\"o}dinger equation. A method of high-intensity femtosecond pulse\nformation can be developed on that basis.",
