... raw output of an excimer laser is a quasi-rectangular beam, typically around 8 × 20 mm, with a near-Gaussian profile in the short axis, and a "top hat" (super Gaussian) profile in the long axis. Top hat refers to a beam intensity cross section with an extended central plateau that falls off ...

... . A typical excimer laser beam has a large, rectangular cross-section (about 8 × 20 mm), with a near-Gaussian profile in the short axis, and a "top hat" profile in the long axis. Top hat refers to a beam intensity with an extended central plateau that falls off near the edges. Beam divergence ...

... Pro exhibits the rectangular near-field beam intensity distribution which is typical for excimer lasers. Along the vertically aligned long axis a top-hat profile is obtained, whereas along the horizontally aligned short axis the energy distribution has a near-gaussian shape. In figure 4, the false color ...

... hours represents nothing less than the basis to the reproducible tayloring of smart thin films via pulsed laser deposition. Only a homogeneous flat-top energy distribution of the excimer laser beam imaged down to a homogeneous area of ca. 2 mm2 onto the target can avoid uncontrolled subsurface boiling ...
