Fusion-point-free fiber laser

Номер: CN212935129U

The fusion-point-free optical fiber laser comprises a laser oscillator, and all devices in the laser oscillator are manufactured on the same gain optical fiber to achieve fusion point free. Furthermore, the laser amplifier is further included, and all devices in the laser oscillator and the laser amplifier are manufactured on the same gain optical fiber to achieve no welding point. And the high-reflection grating and the low-reflection grating are both inscribed on the gain optical fiber based on a femtosecond laser phase template dynamic inscribing method. The pumping beam combiner adopts a side pumping mode, and drawing of the side pumping beam combiner is directly completed on the gain optical fiber in a fused biconical taper mode. Through the mode, all welding points in the laser system can be effectively avoided, so that the heating condition of the system is effectively reduced, the output power of the laser is further improved, and meanwhile, the stability and the reliability of ...
