Description

Technical Field

[0001] This invention relates to the field of laser technology, and in particular to an adjustable saturable absorber reflector fiber optic device. Background Technology

[0002] Saturable absorber (SESAM) fiber optic devices are widely used in ultrafast lasers and are core components. Existing SESAM devices are fixed, with the focusing collimator and SESAM sheet coupled to the optimal position and fixed by soldering. After encapsulation, the SESAM sheet cannot be moved. Once the SESAM sheet is burned out, if the unburned area is to be reused, the entire device must be disassembled, and the SESAM sheet must be removed and remanufactured. Since SESAM sheets tend to burn out after 1-2 years of use, requiring remanufacturing, it is time-consuming and increases operating costs. To address these issues, we propose an adjustable SESAM fiber optic device. Summary of the Invention

[0007] Preferably, the inner wall of the outer sealing box is fixedly connected to an annular slide rail, and the inner wall of the annular slide rail is slidably connected to two second sliders. The sides of the two second sliders that are close to each other are fixedly connected to the sides of the two support plates that are far apart from each other.

[0008] Preferably, a U-shaped plate is fixedly connected to the bottom surface of the outer sealing box, a top block is slidably connected to the inner wall of the U-shaped plate, a spring is fixedly connected to the right side of the top block, and the right end of the spring is fixedly connected to the inner side wall of the U-shaped plate.

[0009] Preferably, the bottom surface of the U-shaped plate has a sliding opening, and a lever plate is slidably connected to the inner wall of the sliding opening. The bottom end of the lever plate extends to the bottom of the U-shaped plate, and the upper surface of the lever plate is fixedly connected to the bottom surface of the top block.

[0010] Preferably, an information panel is provided on the front of the outer packaging box, and the back of the information panel is fixedly connected to the front of the outer packaging box.

[0011] Preferably, the upper surface and the bottom surface of the outer sealing box are both fixedly connected to mounting plates, and each mounting plate has two mounting holes on its right side.

[0013] The technical effects and advantages of this invention are as follows:

[0014] 1. A coated glass plate of a certain thickness is inserted between the collimator of the focusing spot and the SESAM plate, and the glass plate is tilted at a certain angle. The principle of translating the outgoing light path relative to the incident light path is realized by using the angle of the incident light to refract the light onto the parallel plate. Then, rotating the adjustment rod can control the rotation of the rotating ring through the cooperation of the first gear, the second gear, the third gear and the tooth groove. This allows the coated glass plate to rotate the light spot at different positions on the surface of the SESAM plate, thus utilizing different areas of different SESAM plates. Once the SESAM plate is burned out, the customer can rotate the glass plate support to replace the SESAM plate area and continue to use it without returning the parts to the factory for repair, saving time and costs.

[0015] 2. The top plate can be moved in conjunction with the spring force, thereby positioning the adjusting rod and preventing it from rotating during use, which would affect the normal use of the SESAM sheet. Furthermore, the cooperation of the annular slide rail and the second slider can prevent the support plate from shaking and affecting the coated glass sheet. Attached Figure Description
