Laser diode system with cooling subsystem for cooling laser emitter
A recently granted patent (Publication Number: US11962129B2) discloses a laser diode system designed for efficient cooling. The system includes a substrate with a laser diode emitter emitting a laser beam from a facet, along with a cooling subsystem featuring cooling fins that form elongated channels for circulating a cooling fluid. The cooling fluid flows over the facet of the laser diode emitter, ensuring effective cooling of both the emitter and the substrate. Additionally, a container filled with the cooling fluid fully submerges the laser diode emitter, enhancing the cooling process.
Furthermore, the patent describes a method for cooling the laser diode system, involving the arrangement of a cooling subsystem in contact with the substrate of the laser diode emitter. The cooling fluid is circulated through elongated channels formed by fins of the cooling subsystem, with the fluid flowing over the facet of the laser diode emitter. The system is designed to optimize cooling efficiency by ensuring proper circulation of the cooling fluid and maintaining contact with the emitter-side of the substrate. The cooling subsystem is manufactured as a single monolithic section from materials such as Silicon, Silicon-Carbide, Copper-Tungsten, Copper-Diamond, or Gallium Arsenide, highlighting the versatility and adaptability of the system for various applications in laser technology.
