[0002] The laser usually includes a pump source for emitting pump laser, and an optical fiber connected to the output end of the pump source, which is wound on a fiber reel. When the laser is working normally, the pump source and the fiber reel usually need to be cooled to avoid damage to the pump source and the optical fiber due to excessive temperatures. During normal operation of the laser, the pump source will generate more heat than the optical fiber on the fiber reel, so the pump source needs to be cooled faster. The optical fiber wound on the fiber reel needs to avoid condensation, so it is necessary to avoid condensation on the optical fiber due to the temperature of the fiber reel being too low.

[0003] However, existing lasers generally use the same cooling component to cool the pump source and the fiber reel at the same time, resulting in insufficient cooling temperature for the pump source, or the temperature of the fiber reel is too low and condensation occurs on the fiber surface, making it impossible to cool the pump source and the fiber reel at the same time.

[0026] The embodiments of the present application provide a laser, which is described in detail below.

[0027] Figure 1 This is a schematic diagram of the structure of an embodiment of the laser provided in the present application. Figure 1As shown, the laser 100 includes a cabinet 110, a pump assembly 120 and an installation assembly 130. The cabinet 110 includes an installation cavity 111. The pump assembly 120 and the installation assembly 130 are installed in the installation cavity 111 of the cabinet 110. The pump assembly 120 includes a pump source 121 and a first cooling member 122 connected to each other. The first cooling member 122 is used to cool the pump source 121, and the pump source 121 is used to emit pump light. The installation assembly 130 includes a second cooling member 131, an optical fiber disc 132 and an electrical device 133. The optical fiber disc 132 and the electrical device 133 are respectively connected to the second cooling member 131. The optical fiber disc 132 is used to coil the optical fiber connected to the pump source 121. The electrical device 133 is electrically connected to the pump source 121.

[0028] The laser 100 provided in the embodiment of the present application cools the pump source 121 through the first cooling member 122, and cools the optical fiber disc 132 and the electrical device 133 through the second cooling member 131, so that the first cooling member 122 and the second cooling member 131 can cool the pump source 121 and the optical fiber disc 132 at different temperatures respectively, so that the pump source 121 can be reduced to a lower temperature to ensure the performance of the pump source 121, while the temperature of the optical fiber disc 132 is not reduced too low, so as to avoid the temperature of the optical fiber wound on the optical fiber disc 132 being too low and generating condensed water. Therefore, the laser 100 provided in the embodiment of the present application can take into account the cooling of the pump source 121 and the optical fiber disc 132 at the same time.

[0029] On this basis, the embodiment of the present application also cools the electrical device 133 through the second cooling member 131, which can reduce the temperature of the electrical device 133 and prevent the temperature of the electrical device 133 from being too low, thereby causing condensed water to form on the surface of the electrical device 133, further improving the working stability of the laser 100.

[0030] In some embodiments, the first cooling member 122 may include a first cooling channel 1221, and the second cooling member 131 may include a second cooling channel 1311. The laser 100 may further include a refrigerant supply assembly 140, which is in communication with the first cooling channel 1221 and the second cooling channel 1311. The refrigerant supply assembly 140 is used to supply refrigerant to the first cooling channel 1221 of the first cooling member 122, so that the refrigerant and the first cooling member 122 perform heat exchange to reduce the temperature of the first cooling member 122, thereby cooling the pump source 121 through the first cooling member 122. At the same time, the refrigerant supply assembly 140 is also used to supply refrigerant to the second cooling channel 1311 of the second cooling member 131, so that the refrigerant and the second cooling member 131 perform heat exchange to reduce the temperature of the second cooling member 131, thereby cooling the optical fiber disk 132 and the electrical device 133 through the second cooling member 131. The refrigerant may be a refrigerant, cooling water or other liquid or gas that can cool the first cooling element 122 and the second cooling element 131 .

[0031] In some embodiments, the refrigerant supply assembly 140 is used to supply a refrigerant of a first temperature to the first cooling channel 1221 of the first cooling member 122, and the refrigerant supply assembly 140 is used to supply a refrigerant of a second temperature to the second cooling channel 1311 of the second cooling member 131, wherein the first temperature is lower than the second temperature. That is, the temperature of the refrigerant supplied by the refrigerant supply assembly 140 to the first cooling channel 1221 of the first cooling member 122 is lower than the temperature of the refrigerant supplied to the second cooling channel 1311 of the second cooling member 131, thereby making the temperature of the first cooling member 122 lower than the temperature of the second cooling member 131, so that the first cooling member 122 can reduce the pump source 121 to a lower temperature, and at the same time, the temperature of the optical fiber disk 132 will not be too low.

[0032] In some embodiments, Figure 1 As shown, the refrigerant supply assembly 140 may include a refrigerant supply component 141, which is connected to the first cooling channel 1221 and is used to supply a refrigerant of a first temperature to the first cooling channel 1221. Thus, the first cooling member 122 can be cooled more quickly by the refrigerant, so that the temperature of the first cooling member 122 is lower.

[0033] Specifically, the outlet of the refrigerant supply component 141 is connected to the inlet of the first cooling channel 1221 of the first cooling member 122, and the inlet of the refrigerant supply component 141 is connected to the outlet of the first cooling channel 1221 of the first cooling member 122, so that the refrigerant supply component 141 circulates to supply refrigerant to the first cooling channel 1221 of the first cooling member 122.

[0034] At the same time, the refrigerant supply assembly 140 can include a cooling water supply component 142, which is connected to the second cooling channel 1311 and is used to supply cooling water of a second temperature to the second cooling channel 1311, thereby reducing the speed of reducing the temperature of the second cooling member 131 and making the temperature of the second cooling member 131 higher than that of the first cooling member 122, thereby avoiding the generation of condensed water on the surface of the optical fiber on the optical fiber reel 132.

[0035] Specifically, the outlet of the cooling water supply component 142 can be connected to the inlet of the second cooling channel 1311 of the second cooling member 131, and the inlet of the cooling water supply component 142 can be connected to the outlet of the second cooling channel 1311 of the second cooling member 131, so that the cooling water supply component 142 circulates and supplies cooling water to the second cooling channel 1311 of the second cooling member 131.

[0036] In other embodiments, Figure 2 As shown, the refrigerant supply component 140 can also be enabled to simultaneously supply refrigerant at a first temperature and refrigerant at a second temperature, and the outlet of the refrigerant supply component 140 for supplying the first temperature refrigerant is connected to the inlet of the first cooling channel 1221 of the first cooling member 122, while the outlet of the refrigerant supply component 140 for supplying the second temperature refrigerant is connected to the inlet of the second cooling channel 1311 of the second cooling member 131, thereby supplying two refrigerants of different temperatures to the first cooling channel 1221 of the first cooling member 122 and the second cooling channel 1311 of the second cooling member 131.

[0037] The outlet of the first cooling channel 1221 of the first cooling member 122 and the outlet of the second cooling channel 1311 of the second cooling member 131 are respectively connected to the inlet of the refrigerant supply assembly 140, so that the refrigerant in the first cooling channel 1221 of the first cooling member 122 and the refrigerant in the second cooling channel 1311 of the second cooling member 131 flow back into the refrigerant supply assembly 140. The refrigerant of the first temperature supplied by the refrigerant supply assembly 140 to the first cooling channel 1221 of the first cooling member 122 and the refrigerant of the second temperature supplied to the second cooling channel 1311 of the second cooling member 131 can be a refrigerant or cooling water, which is not limited here.

[0038] In addition, the outlet of the refrigerant supply assembly 140 can be communicated with the inlet of the first cooling channel 1221 of the first cooling member 122, and the outlet of the first cooling channel 1221 of the first cooling member 122 can be communicated with the inlet of the second cooling channel 1311 of the second cooling member 131. Thus, the refrigerant supply assembly 140 can supply a refrigerant of a first temperature to the first cooling channel 1221 of the first cooling member 122, and when the refrigerant of the first temperature exchanges heat with the first cooling member 122, the temperature will increase to become a refrigerant of a second temperature, and the refrigerant of the second temperature flows from the outlet of the first cooling channel 1221 of the first cooling member 122 into the second cooling channel 1311 of the second cooling member 131, so as to supply the refrigerant of the second temperature to the second cooling channel 1311 of the second cooling member 131.

[0039] Among them, the outlet of the second cooling channel 1311 of the second cooling member 131 is connected to the inlet of the refrigerant supply assembly 140, so that the refrigerant at the second temperature can flow back to the refrigerant supply assembly 140 from the outlet of the second cooling channel 1311 of the second cooling member 131 after heat exchange with the second cooling member 131.

[0040] In some embodiments, the optical fiber tray 132 and the electrical device 133 of the mounting assembly 130 can be distributed on opposite sides of the second cooling member 131 to avoid mutual interference between the optical fiber on the optical fiber tray 132 and the electrical device 133. Specifically, the optical fiber tray 132 can be located above the second cooling member 131, and the electrical device 133 can be located below the second cooling member 131. Alternatively, the optical fiber tray 132 can also be located below the second cooling member 131, and the electrical device 133 can be located above the second cooling member 131.

[0041] In some embodiments, Figure 1 As shown, the distribution direction of the pump assembly 120 and the mounting assembly 130 can be made to form an angle with the height direction of the cabinet 110 to reduce the height of the cabinet 110. Specifically, the distribution direction of the pump assembly 120 and the mounting assembly 130 is perpendicular to the height direction of the cabinet 110. The first cooling member 122 is arranged in a plate shape, and the plate surface of the first cooling member 122 is perpendicular to the height direction of the cabinet 110. The pump source 121 is installed on the lower surface of the first cooling member 122. The second cooling member 131 is arranged in a plate shape, and the plate surface of the second cooling member 131 is perpendicular to the height direction of the cabinet 110. The optical fiber disc 132 and the electrical device 133 are installed on the opposite side plates of the second cooling member 131.

[0042] Or, if Figure 2As shown, the pump assembly 120 and the mounting assembly 130 can be distributed in sequence along the height direction of the cabinet 110 to reduce the width of the cabinet 110 in the lateral direction. Specifically, the pump assembly 120 is located below the mounting assembly 130. The distribution direction of the pump assembly 120 and the mounting assembly 130 is parallel to the height direction of the cabinet 110.

[0043] In some embodiments, Figure 1 and Figure 2 As shown, the laser 100 includes a water receiving member 150 located below the pump assembly 120, and the water receiving member 150 includes a water receiving groove 151, and the water receiving groove 151 is used to receive the condensed water dripping from the pump assembly 120 to prevent the condensed water generated by the pump assembly 120 from dripping into the installation cavity 111 of the cabinet 110. The water receiving member 150 is located in the installation cavity 111 of the cabinet 110. The laser 100 also includes a drain pipe 152, one end of which is connected to the water receiving groove 151 of the water receiving member 150, and the other end of the drain pipe 152 extends out of the cabinet 110 to discharge the condensed water in the water receiving groove 151 to the outside of the cabinet 110.

[0044] In some embodiments, the surface of the connection point (not shown in the figure) of the pump source 121 may be wrapped with an insulating portion (not shown in the figure). Thus, it is possible to prevent the condensed water generated on the surface of the pump source 121 from flowing to the connection point of the pump source 121, thereby causing a short circuit at the connection point of the pump source 121. Among them, an insulating coating may be applied on the surface of the connection point of the pump source 121 to form an insulating portion; or, an insulating glue may be applied on the surface of the connection point of the pump source 121 to form an insulating portion.
