Self-photopumped Ne-like and Ni-like X-ray laser

Date Do, 14.11.2013 - Do, 14.11.2013
Time 10.15

Program The very successful collisional excitation scheme has been studied for decades and several pump techniques have been developed such as grazing-incidence pumping (GRIP), multipulse pumping and traveling wave excitation (TWE). The pumping mechanism is not necessarily limited to the collisional excitation scheme. A self-photopumped mechanism has already been proposed, but the requirement of high intensity has always been an issue. Since the CPA technique has been well developed, Terawatt infrared pump pulses are accessible on the lab scale. Applying those already matured pump technologies, one can achieve lasing on the „self-photopumped“ 3d -> 3p and the 4f -> 4d laser lines for Ne- and Ni- like ions, respectively. I will mainly focus on presenting results achieved on photopumped laser lines for materials in the Ne-like and the Ni-like ionization states.
