中文摘要
相较于传统的可见光半导体激光器和全固态激光器及其倍频,可见光光纤激光器具有结构简单、性能稳定和光束质量好等优点,在科学研究和工业制造领域有广泛的应用前景。然而,目前实现的可见光光纤激光器的输出功率和转换效率均较低。得益于逐渐成熟的蓝光激光二极管(LD)工艺,本项目拟采用直接蓝光LD包层泵浦设计,结合激光腔内增益竞争机制,研究高效率、高功率可见光Ho3+/Pr3+共掺氟化物光纤激光的新方法,并解决其关键技术。主要包括:1)基于蓝光LD泵浦机制,分析基态重吸收效应,优化激光腔镜设计,实现高效率、高功率绿光光纤激光器;2)在蓝光LD泵浦条件下,研究Ho3+/Pr3+共掺有效能量转换机制,实现高效率、高功率深红光光纤激光器;3)在可见光激光腔内插入波长选择器件,实现宽带调谐的绿光和深红光光纤激光器。这一项目将促进高功率可见光光纤激光器的发展,为实现成本低廉和性能优良的波长调谐可见光激光器奠定基础。
英文摘要
Compared to conventional visible semi-conductor lasers and all-solid-state lasers with its frequency doubling, visible fiber lasers hold a series of advantages including structure simplicity, performance stability, and good beam quality, thus reinforcing their widespread practical applications in scientific research and industrial manufacturing. However, the available visible fiber lasers so far operate at low output power and low conversion efficiency. Benefit from commercial blue laser diode (LD), efficient high-power visible Ho3+/Pr3+ co-doped fluoride fiber lasers directly cladding-pumped with blue LD are proposed under an intracavity gain competition medium in this project, which resolves their critical technology. The main details are as follows: 1) Based on a blue-LD pump, the combination of analyzing the reabsorption effect and optimizing the design of laser cavity mirrors leads to an efficient high-power green fiber laser. 2) Under a blue-LD pumping, an efficient energy transfer within Ho3+/Pr3+ co-doped ions is investigated, which contributes to an efficient high-power deep-red fiber laser. 3) By the insertion of wavelength selective elements into visible laser resonator, widely tunable green and deep-red fiber lasers are implemented. This project could facilitate the development of high-power visible fiber lasers, laying the foundation of cost-effective and high-performance tunable visible lasers.
