HIGH SPEED LIGHT VALVE SYSTEM

An additive manufacturing system includes a high power laser to form a high fluence laser beam. A 2D patternable light valve having a structure responsive to electron emission is positioned to receive and pattern light received from the high power laser. Un système de fabrication additive comprend u...

Zusammenfassung:	An additive manufacturing system includes a high power laser to form a high fluence laser beam. A 2D patternable light valve having a structure responsive to electron emission is positioned to receive and pattern light received from the high power laser. Un système de fabrication additive comprend un laser haute puissance destiné à former un faisceau laser à fluence élevée. Un modulateur de lumière pouvant former des motifs en 2D qui présente une structure sensible aux émissions d'électrons est positionné de façon à recevoir et à modeler la lumière reçue du laser haute puissance.
