We present two-dimensional, high-resolution, spatial images of the 196-{Angstrom} laser emission from the output aperture of a neonlike germanium laser which is created by illuminating a slab target with a series of short 100-ps pulses from the Nova laser. Simulations of the gain which are propagated through the plasma density gradients to calculate the spatial distribution of the laser intensity are compared with the experiments and show good agreement. The importance of refraction in the propagation calculation manifests itself in the laser intensity peaking 150 {mu}m from the target surface, even though the gain peaks 50 to 60 {mu}m from the target surface. {copyright} {ital 1997} {ital The American Physical Society}
