Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber collimators, and more specifically, particularly relates to an optical fiber collimator with pluggable optical fibers. Background Art

[0002] Compared with gas lasers and solid-state lasers, the biggest feature of semiconductor lasers is wavelength diversity. By adjusting the material and thickness of the active area material, the laser wavelength can cover almost the entire wavelength range. It not only has a high electro-optical conversion efficiency but can also be monolithically integrated, making it suitable for large-scale production. Fiber collimators are basic optical components necessary for the output of semiconductor fiber lasers. They can couple the parallel light beams from multiple pump chips into optical fibers.

[0003] In the existing optical fiber detachable and pluggable collimator structure, after the optical fiber end plug is connected to the socket on the collimator, the optical fiber plug may become loose after connection due to the lack of a stable retaining structure at the socket, which will affect the precise coordination between the optical fiber collimator and the optical fiber.

[0004] In summary, the utility model provides a pluggable optical fiber collimator to solve the above problems. Utility Model Content
