Research Progress of Key Laser Materials in 900 nm Band
Nd3+ 900 nm laser can be used for pumping Yb3+ laser materials and atmospheric detection. The deep blue laser produced by its frequency doubling has important applications in underwater communications, atomic cooling, biomedicine, laser storage, laser display, and laser processing. However, the realization of Nd3+ 900 nm laser must overcome the problem of Nd3+ 1060 nm transition competition. This article introduces the development history of various Nd3+-doped laser materials 900 nm laser, and briefly summarizes the methods to suppress 1060 nm laser. Combined with the research work of our research group, this article proposes that the key to further increasing the output power of the Nd3+ 900 nm laser is to ensure a lower quenching probability and increase the 900 nm fluorescence branching ratio of the material. By incorporating non-oxygen anion groups into Nd3+ silica glass to adjust the Nd3+ micro-local environment, the Nd3+ 900 nm fluorescence branching ratio is greatly improved. Nd3+-doped fiber with a core-to-clad ratio of 20/125 μm was drawn from the preform with this silica glass as the core. Preliminary master oscillation power amplification results showed that the fiber had a good inhibition effect on amplified spontaneous emission at 1060 nm. This provides a new method for realizing Nd3+ 900 nm high-power laser.
