Abstract
Optical-field-ionization collisional-excitation x-ray lasers in xenon and krypton clustered gas jets were experimentally investigated in detail. Dependence of x-ray lasing on atom density, laser focus position, and laser polarization ellipticity was mapped out to find the optimal lasing conditions, and a tomographic measurement technique was used to provide clear pictures of the x-ray amplification process.
