摘　　要：We have successfully generated a 1.3/1.4μm random fiber laser(RFL)using bismuth(Bi)-doped phosphosilicate fiber.The Bi-doped RFL has shown excellent long-term operational stability with a standard deviation of approximately 0.34%over 1 h at a maximum output power of 549.30 mW,with a slope efficiency of approximately 29.21%.The Bi-doped phosphosilicate fiber offers an emission spectrum ranging from 1.28 to 1.57μm,indicating that it can be tuned within this band.Here,we demonstrated a wavelength-tuning fiber laser with a wavelength of 1.3/1.4μm,achieved through the using of a fiber Bragg grating or a tunable filter.Compared to traditional laser sources,the RFL reduces the speckle contrast of images by 11.16%.Due to its high stability,compact size,and high efficiency,this RFL is highly promising for use in biomedical imaging,communication,and sensor applications.
