摘要

演示了一种二极管泵浦连续波（CW）Nd:Na2La4(WO4)7 (Nd:NLW)激光器，其工作波长为 0.9 μm，处于 4F3/2 → 4I9/2 转变阶段。通过旋转腔内双折射滤波器（BF）获得了四个单一波长（σ偏振波长为 889 nm 和 912 nm，π偏振波长为 890 nm 和 905 nm）。在 808 nm 波长处的吸收泵浦功率为 17.4 W 时，912 nm 波长处的单波长最高输出功率为 3.4 W。此外，还分别实现了 σ 偏振下 889 和 912 nm 波长处的双波长，以及 π 偏振下 890 和 905 nm 波长处的双波长。据我们所知，这是第一台工作在 0.9 μm 波长的准三级 Nd:NLW 激光器。

Quasi-three-level continuous wave Nd:Na2La4(WO4)7 lasers at 0.9 μm

A diode-pumped continuous wave (CW) Nd:Na₂La₄(WO₄)₇ (Nd:NLW) laser operating at 0.9 μm on ⁴F_3/2 → ⁴I_9/2 transition was demonstrated. Four single- wavelengths (the 889 nm and 912 nm in σ-polarization, the 890 nm and 905 nm in π-polarization) were obtained by rotating an intracavity birefringent filter (BF).

At an absorbed pump power of 17.4 W at 808 nm, the highest output power of single-wavelength at 912 nm was 3.4 W. Furthermore, the dual-wavelength at 889 and 912 nm in σ-polarization and the dual-wavelength at 890 and 905 nm in π-polarization were also achieved, respectively. At an absorbed pump power of 17.4 W, the maximum total output powers of the dual-wavelengths at 889 and 912 nm was 2.12 W. To the best of our knowledge, this is the first quasi-three-level Nd:NLW laser operating at 0.9 μm.

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
