Ne-like Ge 19.6 nm X-ray laser driven by 2ω1ω pumping scheme

Theoretical study of Ne-like X-ray laser may provide insight into the Ni-like X-ray laser.A series of TCE(transient collisional excitation) Ne-like Ge X-ray laser experiments driven by 2ω1ω pulses were designed and the Ne-like Ge 19.6 nm X-ray laser produced in this way was modeled with the newly developed code series.The plasma status in the gain region was presented and the characteristics of the X-ray laser compared to that of the X-ray laser driven by the 1ω1ω driving scheme was given.
