Dye lasing arrangement including an optical assembly for altering the cross-section of its pumping beam and method
This patent describes a lasing arrangement in which a continuous stream of dye is caused to flow through a lasing zone in a cooperating due chamber while the lasing zone is being illuminated by a pumping beam having an initially produced cross-sectional configuration, which beam is directed through a dye chamber window into the lasing zone causing the dye therein to lase and thereby produce or amplify a dye beam, an optical assembly for altering the initially produced cross-sectional configuration of the pumping beam such that the pumping beam enters the dye chamber with an altered cross-sectional configuration corresponding generally to the cross-sectional configuration of the dye chamber window. It comprises first optical means; and second optical means.
