Solid-state laser and x-ray laser research activities at the Institute for Solid State Physics of the University of Tokyo are reviewed. A description of the four-beam multi-TW neodymium- doped phosphate glass (Nd:Glass) laser system is given. Advanced laser research, such as the development of a table-top ultra-short pulse TW Nd:Glass system and phase conjugate system, are also reviewed. Studies on recombination pumped soft x-ray lasers with He-like ions are presently underway. Picosecond x-ray spectroscopy of laser produced aluminum plasmas revealed population inversions between the n equals 3 - 2 levels of He-like Al ions. Details on the first observation of amplification in a recombination pumped He-like soft x-ray laser, showing a time-resolved small-signal gain of 3 cm-1 for the 31D - 21P transition of He-like N, are also given.
