The possible use of laser pulses to create artificial reference stars is assessed. Preliminary estimates concerning the use of a laser probe as a reference star suitable for adaptive optical corrections of seeing suggest that the approach may be feasible; laboratory simulations show that the laser spot can serve as a Hartmann source. It appears that backscattered laser light from atmospheric layers at altitudes of 15-100 km can provide enough photon events to activate a fast seeing correction system. With an array of projected spots, the isoplanatic field can be improved substantially. Considerable gains in sensitivity and limiting magnitude can be expected for large ground-based telescopes such as the VLT and the NNTT if laser shooting techniques can be implemented.
