Title:
LASER MODULE STRUCTURE WITH OPTICAL FEEDBACK
Document Type and Number:
WIPO Patent Application WO/2013/159456
Kind Code:
A1
Abstract:
A laser module structure with optical feedback comprises a laser emitter (1), a photoelectric detector (2), and an optical lens (3). The laser emitter (1) is capable of emitting laser beams with a certain divergence angle to the photoelectric detector (2), the photoelectric detector (2) converts part of the laser beams into electrical signals for feedback control, and the other laser beams are output through the optical lens (3). The laser module structure does not need an optical filter or a splitter and a support thereof, and is capable of simplifying a laser module structure, reducing the length and the volume of a laser module structure, decreasing costs, and improving an output ratio of the laser.
