A wavelength switchable laser (10) of this invention is based on a solid-state laser source (12) in which a fourth harmonic UV laser beam (26) is ordinarily used for processing, and a second harmonic "green" laser beam (28) is dumped and wasted. However, thisinvention uses the ordinarily wasted green laser beam for processing ECB (30) conductor layers (32, 36), which enhances processing throughout because of the higher power of thegreen energy than of the UV energy. A Pockel cell (16) effects laser beam polarizationswitching that causes either the green beam or the UV beam to be directed to the ECB forprocessing different materials. This invention requires only a single rail laser source and is, therefore, simple, cost effective, efficient, inherently aligned, and has high processing throughput.

L'invention concerne un laser commutable en longueur d'onde (10) basé sur une source de laser à l'état solide (12) dans laquelle un quatrième faisceau laser UV harmonique (26) est habituellement destiné à un traitement, un second faisceau laser "vert" harmonique (28) étant émis à perte. Toutefois, cette invention permet d'utiliser le faisceau laser vert normalement perdu pour traiter des couches conductrices (32, 36) de carte à circuit gravé (30), ce qui améliore le traitement étant donné la puissance supérieure de l'énergie verte par rapport à l'énergie UV. Une cellule de Pockel (16) produit une commutation de polarisation de faisceau laser amenant le faisceau vert ou le faisceau UV à se diriger vers la carte à circuit gravé en vue d'un traitement de différents matériaux. Cette invention ne nécessite qu'une source laser à rail unique. Elle est donc simple, peu coûteuse, efficace et intrinsèquement alignée, et permet d'obtenir une vitesse de traitement élevée.
