Abstract

We demonstrate a diode-pumped continuous-wave tunable orthogonally polarized dual-wavelength Pr:LiGdF4 laser in the green range. The excellent mode matching between the pump and green lasers is achieved under the consideration of thermally induced effects. We analyze the condition of gain-to-loss balance via an uncoated glass etalon to achieve the dual-wavelength operation. At an absorbed pump power of 17.9 W, a dual-wavelength laser operating at 546 nm in π-polarization and 538 nm in σ-polarization with 1.72 W of average output power was obtained. Orthogonally polarized dual-wavelength laser operation at shorter- or longer-wavelength pairs with lower average output power could also be realized for other output-coupling transmissions. To the best of our knowledge, this is the first work realizing orthogonally polarized dual-wavelength operation in Pr:LiGdF4 lasers.

绿色范围内的正交偏振双波长 Pr:LiGdF4 激光器

我们展示了一种绿光范围内的二极管泵浦连续波可调正交偏振双波长 Pr:LiGdF4 激光器。考虑到热诱导效应，泵浦激光器和绿光激光器之间实现了出色的模式匹配。我们分析了通过无涂层玻璃蚀刻管实现双波长工作的增益-损耗平衡条件。在吸收泵浦功率为 17.9 W 的情况下，我们获得了工作在 π 偏振波长 546 nm 和 σ 偏振波长 538 nm 的双波长激光器，其平均输出功率为 1.72 W。在其他输出耦合传输中，也可以在较短或较长的波长对上以较低的平均输出功率实现正交偏振双波长激光器运行。据我们所知，这是首次在 Pr:LiGdF4 激光器中实现正交偏振双波长运行的工作。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
