Recent progress in the development of XUV lasers by research teams usi
ng high-power and ultrashort-pulse Nd:glass and KrF laser facilities a
t the Rutherford Appleton Laboratory is reviewed. Injector-amplifier o
peration and prepulse enhanced output of the Ge XXIII collisional lase
r driven by a kilojoule glass laser, enhanced gain in CVI recombinatio
n with picosecond CPA drive pulses from a glass laser, and optical fie
ld ionization and XUV harmonic generation with a KrF CPA laser are des
cribed.
