Experimental Analysis of High-Power Cladding Power Stripper Based on Segmented Corrosion
To enhance the beam quality,reduce manufacturing costs,and prevent overheating during cladding power stripping,this study utilizes a domestic 20/400 μm energy transmitting fiber.A cost-effective glass etching cream(TMS-307)serves as the etching agent.By applying segmented etching,a cladding power stripper with five symmetrically structured sections,each 5 cm long,is developed.Tests of the cladding power stripper,both in forward and reverse configurations,reveal that with an input power of 488 W,the output power is approximately 15.3 W,and the power stripping efficiency reaches 15 dB.Notably,without water-cooling,the peak operating temperature at the laser input terminal of the stripper remains stable around 120℃.The temperature distribution is relatively uniform,with no significant hot spots detected.These results indicate that the cladding power stripper successfully meets the demands of high-power fiber lasers,offering cost reduction,improved beam quality,and enhanced stability.
