Abstract:
A system includes a laser system having a master oscillator (102) and a planar waveguide (PWG) amplifier (104) having one or more laser diode pump arrays (208), a PWG pumphead (204-206, 308), input optics (202), and output optics (213, 214). The PWG pumphead is configured to receive a low-power optical beam (1102) from the master oscillator and generate a high-power optical beam (116). The PWG pumphead includes a laser gain medium (1110), a cartridge (206), and a pumphead housing (204). The cartridge is configured to receive and retain the laser gain medium, and the cartridge includes one or more cooling channels (1106-1108) configured to transport coolant in order to cool the laser gain medium. The pumphead housing is configured to receive and retain the cartridge, where the cartridge is removable from the housing.
Abstract:
A method includes forming a coating (106a, 106b, 306a, 306b) that covers at least part of a conduction substrate (102a, 102b, 302a, 302b), where the conduction substrate is configured to transport thermal energy. The method also includes forming at least part of an optical waveguide on the coating. The optical waveguide includes multiple cladding layers (108a-108b, 308a-308b) and a core (110, 310), and the optical waveguide is configured to transport optical signals. The conduction substrate, the coating, and the optical waveguide form an integrated monolithic waveguide structure.
Abstract:
A heat sink (106, 106a, 106b) for cooling a laser gain medium (102) includes a coolant channel (112, 112a, 112b), an inlet pore (118, 118a, 118b), an outlet pore (120, 120a, 120b), and a thermal optical interface (TOI) channel (114, 114a, 114b). The coolant channel is configured to receive a coolant for removing heat from the heat sink. The TOI channel is coupled to the coolant channel by the inlet pore and the outlet pore. The TOI channel is configured to receive a portion of the coolant through the inlet pore. The received portion forms an ultra-thin liquid TOI. The TOI channel is further configured to return a portion of the TOI through the outlet pore to the coolant channel.
Abstract:
Die Erfindung betrifft einen Lichtwellenleiter mit wenigstens einem entlang der Längserstreckung des Lichtwellenleiters verlaufenden Kernbereich (1) und einem ersten Mantel (2), der, im Querschnitt des Lichtwellenleiters gesehen, den Kernbereich (1) umschließt. Außerdem betrifft die Erfindung eine optische Anordnung mit einem solchen Lichtwellenleiter sowie Verfahren zur Herstellung des Lichtwellenleiters. Aufgabe der Erfindung ist, einen Lichtwellenleiter für den Hochleistungsbetrieb bereitzustellen, der hinsichtlich Modeninstabilität gegenüber dem Stand der Technik verbessert ist. Diese Aufgabe löst die Erfindung dadurch, dass der Lichtwellenleiter wenigstens im Kernbereich (1) aus kristallinem Material besteht.
