具有线形相阶的相板通常用作激光模式转换器，并允许将拉盖尔-高斯模态从TEM00 转换为更高的模TEM01、TEM11等。例如，这种相位步进模式转换器被应用于光学腔体和谐振器、光学镊子、原子和分子激励等领域。这些相板在表面上有一个物理台阶，其高度可以相对于π移动，这种差异导致台阶区产生破坏性干涉，并在光束轮廓中产生零强度线。

激光模式转换DOE尺寸有两种，一种是11x11x2.5mm，对应的有效孔径是10mmm，另外一种是22x22x2.5 mm，对应的有效孔径是20mm。Vortex激光模式转换器优势在于所有型号都有库存，交期短。Vortex激光模式转换器，能够将基本激光模式TEM_00转换为更高阶的Hermite-Gaussian光束，包括TEM00, TEM01, TEM03, TEM08，和TEM16等。Vortex激光模式转换器的典型的光学设置，通常，激光模式转换器使用的光路结构依次为：单模激光器、激光模式转换器（相位板）、光学元件和显微镜物镜。激光模式转换DOE又可以叫做相位步进模式转换器和mode convertor。
