Abstract

We reported and demonstrated a solid-state laser to achieve controlled generation of order-switchable cylindrical vector beams (CVBs). In the cavity, a group of vortex wave plates (VWPs) with two quarter-wave plates between the VWPs was utilized to achieve mode conversion and order-switch of CVBs. By utilizing two VWPs of 1 st and 3 rd order, the 2 nd and 4 th order CVBs were obtained, with mode purities of 96.8% and 94.8%, and sloping efficiencies of 4.45% and 3.06%, respectively. Furthermore, by applying three VWPs of 1 st , 2 nd and 3 rd order, the mode-switchable Gaussian beam, 2 nd , 4 th and 6 th order CVBs were generated.

由Nd:YAG激光器可控地产生顺序可切换的圆柱形矢量光束

我们报道并演示了一种固体激光器，以实现有序可切换圆柱矢量光束(CVBs)的可控生成。在空腔内，利用一组涡波片(VWPs)，在涡波片之间放置两个四分之一波片来实现CVBs的模式转换和顺序切换。利用1级和3级两个vwp，得到了2级和4级CVBs，模式纯度分别为96.8%和94.8%，倾斜效率分别为4.45%和3.06%。利用1阶、2阶和3阶vwp，分别生成了可切换模式的高斯光束、2阶、4阶和6阶CVBs。

期刊介绍： Chinese Optics Letters (COL) is an international journal aimed at the rapid dissemination of latest, important discoveries and inventions in all branches of optical science and technology. It is considered to be one of the most important journals in optics in China. It is collected by The Optical Society (OSA) Publishing Digital Library and also indexed by Science Citation Index (SCI), Engineering Index (EI), etc. COL is distinguished by its short review period (~30 days) and publication period (~100 days). With its debut in January 2003, COL is published monthly by Chinese Laser Press, and distributed by OSA outside of Chinese Mainland.
