The high-power laser unit technology R&D center of Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, successfully prepared a single-mode laser output silicate all-solid-state photonic crystal fiber with a core diameter of 45 microns by using self-prepared 1.
2wt% neodymium ion-doped N0312 high-quality silicate glass and other commercial undoped silicate glass, through theoretical design simulation, and finally using the combination of tube rod method and stacking method, A single-mode laser output
of 0.
8W is achieved by using a 97cm long optical fiber.
At present, the international mainstream large-mode field photonic crystal fiber focuses on the research of quartz air hole optical fiber, compared with quartz glass, silicate glass has the characteristics of low melting point, high concentration of rare earth ion doping, good uniformity, etc.
, and the use of relatively short fiber can achieve laser output
.
At the same time, the all-solid-state structure in this study is more conducive to the welding of optical fibers and avoids the pollution of the air pore structure
