DETAILED DESCRIPTION

[0037] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not intended to limit the present application.

[0038] It should be noted that when a component is referred to as "fixed to" or "disposed on" another component, it can be directly or indirectly on the other component. When a component is referred to as "connected to" another component, it can be directly or indirectly connected to the other component. The terms "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or position based on the orientation or position shown in the drawings, and are only for the convenience of description, and cannot be understood as a limitation on the technical solutions. The terms "first", "second" are only for the convenience of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. The meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0039] At present, the photoelectric properties and wavelength of the produced laser are generally tested in the industry. The wavelength of the laser is generally tested using a spectrum analyzer, which is not only expensive, resulting in high cost for wavelength testing of the laser, and the spectrum analyzer can test the specific wavelength of the laser during operation, resulting in a long time required for scanning testing when the wavelength of the laser is tested using the spectrum analyzer.

[0040] ​In actual production of the laser, since the wavelength of the laser ranges from 127nm to 1610nm, there is one type every 20nm, and the product appearance features are consistent and cannot be distinguished. In order to ensure that the produced lasers are not mixed (that is, different wavelength lasers are not mixed together), if the above process is used to test the wavelength of the laser, the cost of testing is high and the efficiency is low, and it cannot be used in batch production.

[0041] To this end, referring to Figure 1 , Figure 2 and Figure 5 , the embodiment of the present application provides a device for checking the mixing of the laser production process, which comprises a light receiver 1 and a filter 2. The light receiver 1 is arranged on the light emitting side of the laser (not shown in the figure), and the filter 2 is arranged between the laser and the light receiver 1. The filter 2 is used to penetrate the light of a predetermined wavelength generated by the laser to be received by the light receiver 1, or to block the light of a non-predetermined wavelength generated by the laser.

[0042] It can be predicted that when the wavelength of the light generated by the laser corresponds to the wavelength type of the filter, the light receiver 1 can receive the light generated by the laser; when the wavelength of the light generated by the laser does not correspond to the wavelength type of the filter, the light generated by the laser will be blocked by the filter, so that the light receiver 1 cannot receive the light generated by the laser. That is, according to whether the light receiver 1 can receive the light generated by the laser, the embodiment can distinguish whether the laser is a laser of the same wavelength category, without detecting the specific wavelength of the laser, so as to check the mixing of the laser production process. The testing cost is low and the efficiency is high, and it can be used in batch production.

[0043] It is worth noting that when the light receiver 1 cannot receive the light generated by the laser, it means that the wavelength of the next laser may be the wavelength of the next stage. Therefore, only the last stage of the laser that meets the conditions needs to be classified, and then the filter is replaced, so that the light receiver 1 can start receiving the light generated by the next stage of the laser.

[0044] Optionally, in an embodiment, the type of the laser can be set as one of an FP laser, a DFB laser, an EML laser or a VCSEL laser.

[0045] Optionally, in an embodiment, the light receiver 1 can be set as one of a PD light receiver 1 or an APD light receiver 1.

[0046] Optionally, in an embodiment, the filter 2 comprises a filter, wherein the model range of the filter can be set as 1270nm-1610nm, and the filter has a model category every 20nm, for example, 1270, 1290, 1310, 1590, 1610.

It is predictable that the optical fiber assembly 3 of the embodiment does not need to be directly connected with the light receiver 1, as long as the light transmitted by the optical fiber assembly 3 can enter the light receiver 1.

[0048] Optionally, referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 , in an embodiment, the device further comprises a filter mounting seat 4, a through hole 41 is formed in the middle of the filter mounting seat 4, an installation groove 42 is formed in the filter mounting seat 4 close to one end of the light receiver 1, the installation groove 42 is in communication with the through hole 41, the filter 2 is arranged in the installation groove 42 and covers the through hole 41, one end of the filter mounting seat 4 is connected with the optical fiber assembly 3, and the other end is connected with the light receiver 1.

[0049] The installation groove 42 of the embodiment can be used to install the filter 2, the through hole 41 of the embodiment can make the light generated by the laser pass through the through hole 41 and be received by the light receiver 1 through the filter 2. When the wavelength of the light generated by the laser is different from the wavelength of the aforementioned laser that meets the condition, since the filter 2 covers the through hole 41, the light generated by the laser must pass through the filtering of the filter 2, so that the filter 2 of the embodiment can obtain accurate results when performing the wavelength screening work of the laser.

[0050] Optionally, in an embodiment, the filter 2 is adhered in the installation groove 42 of the filter mounting seat 4 by glue. It is predictable that one model of the filter 2 corresponds to one filter mounting seat 4, and when the filter 2 needs to be replaced, the filter 2 can be replaced by replacing the filter mounting seat 4.

[0054] Optionally, referring to Figure 1 、 Figure 2 and Figure 6 In an embodiment, the device further comprises a light receiver fixing seat 5, the light receiver fixing seat 5 is provided with a mounting hole (not shown in the figure), one end of the light receiver 1 is arranged in the light receiver fixing seat 5, and the other end of the light receiver 1 is connected with the filter mounting seat 4 through the mounting hole.

[0055] In summary, the application provides a device for checking wrong mixing of materials in the production process of a laser, which comprises a light receiver 1 and a filter 2. The light receiver 1 is arranged on the light emitting side of the laser, and the filter 2 is arranged between the laser and the light receiver 1. The filter 2 is used to transmit the light of a predetermined wavelength generated by the laser so as to be received by the light receiver 1, or to block the light of a non-predetermined wavelength generated by the laser. It can be foreseen that when the wavelength of the light generated by the laser corresponds to the wavelength type of the filter 2, the light receiver 1 can receive the light generated by the laser; when the wavelength of the light generated by the laser does not correspond to the wavelength type of the filter 2, the light generated by the laser will be blocked by the filter 2, so that the light receiver 1 cannot receive the light generated by the laser. That is to say, the application only needs to determine whether the light receiver 1 can receive the light generated by the laser, so as to distinguish whether the laser is a laser of the same wavelength, without detecting the specific wavelength of the laser, so as to check the wrong mixing of materials in the production process of the laser. The testing cost is low and the efficiency is high, and the device can be used in batch production.
