Abstract
In this paper studies of ArF excimer laser ablation of the cornea (in vitro pig) are presented. We investigated the dependence of the etching rate (r) on the incident fluence (t) and the etching depth (/) on the number of shots (n) . It was found that roc ln(4) and / oc n. Ultrafast laser based stroboscopic photographic arrangement was constructed with a temporal resolution of 1 ns. It was found that the velocity of the shock wave generated by the impact of the excimer laser pulse can be as high as 7000 m/s. The ejection of the ablation plume was also observed and the velocity of the plume-front was found to be higher than 600 m/s. The recoil forces of the plume generate a surface wave on the surface of the eye having approximately 5 m/s maximum velocity. The amplitude of the surface wave can be as high as 0.15-0.3 mm.
