请用学术语言润色这句话：20世纪80年代中期随着稀土掺杂石英单模光纤制备技术的逐步成熟在激光技术领域稀土掺杂光纤激光器已经成为研究热点通常由泵浦源、稀土掺杂光纤和谐振腔三部分组成。

In the mid-1980s, with the gradual maturity of the technology for preparing rare earth-doped quartz single-mode optical fibers, rare earth-doped fiber lasers emerged as a research hotspot in the field of laser technology. Typically, a rare earth-doped fiber laser is composed of three parts: a pump source, rare earth-doped fiber, and a resonant cavity.
