Ne-like Ti x-ray laser driven by a single femtosecond laser

The new scheme is presented for Ne-like Ti X-ray laser driven by a single laser pulse. According to the self-similarity method, we analyze the properties of Ne-like Ti slab plasma generated by irradiation of femtosecond laser with various front edges. Scaling laws for the temperature, scale length, and electron density are obtained. The characteristics of scaling laws at different input parameters are analyzed. The results show that X-ray laser can be generated by a single femtosecond laser. During the period of pulse front edge, the characteristics of temperature, scale length, and electron density are affected by the growth tendency of light intensity. The femtosecond laser with a gentle front edge is profitable to drive X-ray laser. Our results provide a new program for experiments using a single laser pulse to drive X-ray laser.
