Embodiment Construction
[0032] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It should be noted that terms such as "first" and "second" are only used for distinguishing descriptions, and should not be understood as indicating or implying relative importance.
[0033] The applicant found that the area of the photosensitive region of a single photodetection module is small, and usually cannot cover the entire diameter of the fiber core (it can be understood that the coverage width of the photosensitive region of a single photodetection module is smaller than the diameter of the fiber core). In a jittering environment, the location where the scattered light is irradiated will also jitter relative to the photosensitive area due to the jittering of the environment. Therefore, in a jittering environment, the intensity of the scattered light collected by the photosensitive area of ...

The invention provides a laser detection device, a fiber laser device and a laser detection method, and relates to the technical field of laser detection. The laser detection device comprises at leasttwo photoelectric detection modules arranged side by side; the at least two photoelectric detection modules are arranged on a detection fiber in the fiber laser device; a main photosensitive region formed by photosensitive regions in the at least two photoelectric detection modules are arranged on a fiber core of the detection fiber; and a coverage width of the main photosensitive region is greater than or equal to the diameter of the fiber core. When the detection fiber transmits a to-be-detected laser generated by the fiber laser device, the at least two photoelectric detection modules areused to generate electric signals corresponding to the laser output power of the fiber laser device respectively according to a scattered light of the to-be-detected laser collected by the respectivephotosensitive regions. The technical problem of low reliability of the collected scattered light can be improved.
Description
technical field [0001] The invention relates to the technical field of laser detection, in particular to a laser detection device, a fiber laser and a laser detection method. Background technique [0002] During the use of the fiber laser, if the laser output power of the fiber laser is not detected, it is easy to have the risk of the laser being burned out because the laser output power is too large. In the prior art, when detecting the laser output power of the fiber laser, the scattered light escaped from the transmission fiber is usually collected to obtain the laser output power of the laser transmitted in the transmission fiber. When collecting scattered light, limited by the existing optical fiber structure, the collected scattered light is easily affected by environmental vibrations, so that the reliability of the collected scattered light is low. Contents of the invention [0003] The present application provides a laser detection device, a fiber laser and a lase...
