摘要

该研究首次提出了一种带内泵浦的连续波(CW)∼2.1 μm 微芯片激光器,其基础是掺杂 Ho3+ 离子的短腔锗酸盐玻璃(GeO2-PbO-Ga2O3-Na2O:GPGN)。Ho3+ 离子的激发采用了 1.94 μm、5 W Tm3+ 光纤激光器。在简单、未优化的平面平行法布里-珀罗腔配置中,激光斜率效率达到 19%。据估计,激光腔内有一个正热透镜,其灵敏系数为 S ∼31 m-1W-1,光路畸变值超过 6 μm。激光结果和热透镜分析表明,通过改进热管理和优化腔体配置,GPGN 是一种很有前途的增益介质,可用于 2.1 μm 附近的微芯片激光操作。

Performance evaluation of ∼2.1 μm microchip laser operation in Ho3+ doped germanate glass
An in-band pumped continuous wave (CW) ∼2.1 μm microchip laser is presented for the first time based on a short cavity Ho3+ doped germanate glass (GeO2-PbO-Ga2O3–Na2O: GPGN). A 1.94 μm, 5 W Tm3+ fiber laser was employed for the excitation of the Ho3+ ions. A 19% laser slope efficiency was achieved in a simple, unoptimized plane parallel Fabry-Perot cavity configuration. A positive thermal lens was estimated in the laser cavity with a sensitivity factor of S ∼31 m−1W−1 and an optical path distortion value exceeding 6 μm. The laser results along with the analysis of the thermal lens indicate that with improved thermal management and an optimized cavity configuration GPGN is a promising gain medium for microchip laser operation around 2.1 μm.

期刊介绍: Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
