High-power, high-efficiency single-frequency DBR fiber laser at 1064 nm based on Yb³⁺-doped silica fiber

Abstract

A high-power, high-efficiency single-frequency fiber laser at 1064 nm was demonstrated based on a distributed Bragg reflector (DBR) all-silica-fiber configuration. A single-frequency laser with an output power of 642 mW and slope efficiency of 66.4% with respect to absorbed pump power was achieved from a 1.2-cm-long commercially available Yb3+-doped silica fiber. To the best of our knowledge, this is the highest single-frequency laser power and efficiency obtained from the DBR all-silica fiber laser. The work presented here paves the way for the development of high-power, robust, and cost-effective single-frequency Yb3+-doped all-silica fiber lasers.

“…Of a diverse range of single-frequency fiber laser technologies, short-linear-cavity distributed Bragg reflector (DBR) fiber lasers draw considerable attention with distinctive advantages, such as compactness, cost efficiency, simplicity, and narrow linewidth [4][5][6][7][8]. Especially in recent years, the commercial availability of high-quality heavily rare-earthdoped fibers facilitates the further development of singlefrequency DBR fiber lasers [9][10][11][12][13][14].…”
