  • Aberration compensated diode-laser stack
    Patent number: 10539805
    Abstract: Optical output beams from a vertical stack of diode-laser bars are focused by a simple focusing lens on an optical axis of the lens. The optical output beams from outlying diode-laser bars in the vertical stack are tilted with respect to the optical axis of the focusing lens such that optical output from the whole vertical stack is brought to a common focus location on the optical axis of the focusing lens.
    Type: Grant
    Filed: January 25, 2017
    Date of Patent: January 21, 2020
    Assignee: Coherent, Inc.
    Inventors: Athanasios Chryssis, Geunmin Ryu, David Schleuning
  • Stackable electrically-isolated diode-laser bar assembly
    Patent number: 10297980
    Abstract: A diode-laser assembly having an electrically isolated diode-laser bar on a cooled base-element is disclosed. The diode-laser bar is electrically isolated from the base-element and electrically isolated from any coolant water, thereby eliminating the need for de-ionized water and mitigating corrosion due to galvanic action. Multiple such diode-laser assemblies are stackable, with small bar-to-bar pitch, enabling a high-current and high-brightness diode-laser stack.
