An optical delivery waveguide for a material laser processing system includes a small lens at an output end of the delivery waveguide, transforming laser beam divergence inside the waveguide into a spot size after the lens. By varying the input convergence angle and/or launch angle of the laser beam launched into the waveguide, the output spot size can be continuously varied, thus enabling a continuous and real-time laser spot size adjustment on the workpiece, without having to replace the delivery waveguide or a process head. A divergence of the laser beam can also be adjusted dynamically and in concert with the spot size.

The present invention provides a novel method for culturing cells as well as a novel method for producing a recombinant protein by culturing cells at large scale (up to 1,500 L nominal volume and 750 L working volume), whereby an inflated bag provides a sterile, disposable cultivation chamber. The inflated bag is partially filled with liquid cultivation media and cells, and placed into a containment vessel. The containment vessel is positioned onto an orbitally shaken platform. The orbital shaking moves the containment vessel and thus the bag and induces thereby motion to the liquid contained therein (“shake mixing”). This motion (caused by orbital shaking) induces a dynamic force field that ensures cell suspension, bulk mixing, and oxygen transfer from the liquid surface to the respiring cells without damaging shear or foam generation.
