Many applications in material science, chemistry, and atomic physics require an X-raysource that has a repetition rate of I Hz to a few kHz. In these fields, a very wide range ofphoton energies is of interest. One application is time-resolved surface photoelectronspectroscopy and microscopy where low energy (< 1i4) pulses are required to avoid spacecharge effects but high-repetition rates (= 1kHz) provide the high average power which isneeded to obtain the desired resolution. In pump-probe experiments, it is desirable to havethe repetition rate of the X-ray source be comparable to the repetition rate of thecorresponding IR, optical, or UV laser. We show that the very high-repetition rate ofsynchrotrons (1-1000 MHz) results in an inefficient use of x rays for these types ofexperiments and that a kHz repetition rate X-ray laser would be an excellent source formany experiments. For some applications, a slower repetition rate of order 1 Hz is adequateprovide the energy per pulse is larger (1 mJ). For example, in photoelectron spectroscopyof free clusters, an X-ray laser can provide the required large number of nearly monoenergetic photons during the short time the clusters can be probed in each formation cycle.In the context of source development, we discuss conventional collisional X-ray laserschemes with mJ output pulses that can operate at Hz repetition rates using a high averagepower driving laser. The near term prospects for high-repetition rate X-ray lasing forphoton energies below 100 eV are very good with higher energy capabilities expected in thefuture. In addition, prospects of table-top size X-ray lasers with kHz repetition rates arepresented.
