Deposition machine Off-line Solution Doping

Off-line Solution Doping is a special equipment for liquid phase doping of loose layer on the inner wall of preform after preform production and deposition. It is suitable for doping various rare earth elements, such as bait doping, mirror doping, etc. It can realize constant temperature auxiliary doping environment from room temperature to 90 ℃, which is beneficial to improve doping efficiency and quality. This type of doper is widely used in the process of doping rare earth elements in the loose layer of laser fiber liner. This process is the most critical process of doping fiber, which directly determines the quality of fiber. Traditional doping process usually leads to uneven doping concentration and low efficiency due to manual intervention, and bad doping environment leads to doping defects. The liquid-phase doping machine solves the undesirable quality problems such as unstable, low efficiency, uneven doping concentration and regional doping defects in the traditional doping process, and is the best choice for doping procedures in enterprises manufacturing fiber lasers and fiber sensors.
