| 1 | High performance visible generation of Ho^(3+)-doped all-fiber lasers显示文摘Direct generation of visible frequency from a compact all-fiber laser while preserving high output characteristics has been a subject of research in laser technology.We investigated the high output performance of all-fiber lasers based on Ho^(3+)-doped ZBLAN fluoride glass fiber especially operating in the deep-red band by pumping at 640 nm.Remarkably,we achieved a maximum continuous-wave output power of 271 m W at 750 nm with a slope efficiency of 45.1%,which represents,to our knowledge,the highest direct output power recorded in an all-fiber laser with a core diameter of less than 10μm in the deep-red band.Additionally,we successfully developed a 1.2μm all-fiber laser pumped by a 640 nm laser.We extensively investigated the correlation between these two-laser generation processes and their performances at 750 nm and 1.2μm wavelengths.By increasing the pumping rate,we observed an efficient recycling of population through a highly excited state absorption process,which effectively returned the population to the upper laser level of the deep-red transition.Moreover,we determined the optimized conditions for such lasers,identified the processes responsible for populating the excited state energy levels,and established the corresponding spectroscopic parameters. | SHUAIHAO JI XUEXIAN LIN BO XIAO ZHONGYU WANG XIUJI LIN ZHIPING CAI | 2023 | Photonics Research2023，11，12： | 0 |
