报道了一种利用光抽运产生高阶厄米-高斯横模的垂直外腔面发射激光器（VECSEL）。在线性腔配置中具有约1068 nm发射的VECSEL芯片能够以瓦特级输出功率提供各种高阶模式。一个非常好的协议之间的建模和实验结果验证的想法支撑的方法。此外，同时激射两个独立的和共线的横模从一个单一的激光腔演示。最后利用一个外接的光栅模式转换器将厄米-高斯模式转换成相应的拉盖尔-高斯模式。
We report a vertical external cavity surface emitting laser (VECSEL) with an optical pumping scheme for the generation of higher order Hermite–Gaussian transverse modes. The VECSEL chip with emission around 1068 nm in a linear cavity configuration is capable of delivering a variety of higher order modes with Watt-level output power. A very good agreement between the modeling and experimental results validate the ideas underpinning the method. Additionally, simultaneous lasing of two independent and collinear transverse modes from a single laser cavity is demonstrated. An external astigmatic mode converter is finally utilized for the conversion of Hermite–Gaussian modes into corresponding Laguerre–Gaussian modes.
