Abstract:

Using the method of optical breakdown clipping on Krypton Fluoride excimer laser, ASE (Amplified Spontaneous Emission) pulse compression technology was studied in this paper. And the liquid medium breakdown depth on the ASE pulse compression effect was analyzed. The initial ASE pulse width was 16.8 ns; the shortest 8.4 ns ASE pulse was obtained in the experiment. The auxiliary beam induced luminescence breakdown was used to study on the law of optical breakdown clipping, and the short 7.3 ns ASE pulse was got. These experimental results proved that the auxiliary beams are useful to accelerating the plasma generation rate and duration. The results ASE pulse compression can be controlled in some degree.
