摘要

我们提出了一种转换环形泵浦光束二极管端泵浦激光器对称性的直接方法。通过在腔体中引入一个étalon，我们观察到在退化和非退化范围内，横向模式剖面的空间对称性从矩形变为圆柱形。我们还模拟了滤波后光束穿过埃塔隆的透射率分布。我们的实验结果表明，这种改变对称性的方法在埃塔隆倾斜过程中保持了相对稳定性。

The symmetry change of the transverse modes in ring-LD end-pumped Nd:YVO4 laser with an étalon

A straightforward method for converting the symmetry of a diode end-pumped laser with an annular pump beam has been proposed. By introducing an étalon into the cavity, we observed a change in the spatial symmetry of the transverse mode profile from rectangular to cylindrical both in degenerate and non-degenerate ranges. A simulation of the transmittance distribution of the beam through the étalon after filtering is given. Our experimental results indicate that this method of altering the symmetry maintains relative stability during the tilting of the étalon.

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.
