摘要
We report a neodymium fiber laser incorporating an all-solid photonic bandgap fiber to suppress the four-level laser transition F-4(3/2)-I-4(11/2). We demonstrate lasing at 907 nm on the three-level transition F-4(3/2)-I-4(9/2) when pumping at 808 nm. The maximum slope efficiency obtained was 32% with a threshold pump power of 70 mW.
