This invention concerns a process useful for increasing the accuracy of the shape of a laser ablated feature formed on a substrate, especially where the substrate is a polymeric article. The process includes irradiating the polymeric article with laser light that has passed through a retardation plate selected from stationary adjustable plates, rotating plates or spinning plates, preferable in multiples of quarter-waves or half-waves. This invention also concerns a laser apparatus useful for making ablated features in a substrate having a radiation source; a mask positioned between the radiation source and a substrate to be irradiated, and a retardation plate which is stationary and adjustable, rotating or spinning plates.

La présente invention concerne un procédé permettant d'améliorer la précision de la forme d'un motif d'ablation laser réalisé sur un substrat, en particulier dans les cas où le substrat est un article polymère. Le procédé consiste à traiter par rayonnement l'article polymère au moyen d'une lumière laser ayant traversé un écran ralentisseur choisi parmi les écrans fixes réglables, les écrans rotatifs ou les écrans tournants, de préférence en multiples de quart d'ondes ou de demi-ondes. L'invention concerne également un appareil laser permettant de réaliser des motifs d'ablation dans un substrat, lequel appareil comprend une source de rayonnement, un masque disposé entre la source de rayonnement et le substrat à traiter par rayonnement, et un écran ralentisseur fixe et réglable, rotatif ou tournant.
