A laser diode device, comprising:
- a laser diode component;
- a lens;
- a first carrying element for receiving the laser diode component and the lens;
- a driving chip;
- and
- a second carrying element receiving the driving chip, disposed below the first carrying element to carry the first carrying element, and electrically connected to the first carrying element;
- wherein the first carrying element comprises:
- a first ceramic carrier;
- a first metal layer disposed on the first ceramic carrier;
