摘要：

A laser deposition arrangement for the preparation of smooth YBa2Cu3Oy and EuBa2Cu3Oy films is presented. An excimer laser beam is split by a knife-edge prism into two beams, which are focused onto two rotating targets oriented perpendicular to each other. The two laser-induced molecular streams collide and form a new stream containing mainly light molecules and almost no droplets. The molecules from this stream deposit on a substrate that is placed in the shadow of the original molecular streams. The use of copper-poor targets prevented the occurrence of precipitates.
