Transient inversion soft X-ray lasers

摘要

The collisionally excited transient inversion scheme is shown tonproduce exceptionally high gain coefficients and gain-length products.nData are presented for the Ne-like titanium and germanium and Ni-likensilver X-ray lasers (XRL's) pumped using a combination of nanosecond andnpicosecond duration laser pulses. This method leads to a dramaticnreduction of the required pump energy and makes down-sizing of XRL'snpossible, an important prerequisite if they are to become commonly usedntools in the long-term
