我们演示了一种在端泵浦固体激光器中激发埃尔米特高斯模式（一个横向维度）的方法。激发是通过光纤耦合激光二极管的离轴泵浦来进行的。随着光纤与光轴的横向距离增加，可以连续观察到厄米高斯模式。该激光器具有可变的 M2 因子，因此可以用作校准目的的 M2 标准。使用此方法可以获得 1 到 190 之间的 M2 因子。
We demonstrate a method for the excitation of Hermite Gaussian modes (one transverse dimension) in end-pumped solid-state lasers. The excitation is performed by pumping off-axis with the help of a fibre-coupled laser diode. With increasing transverse separation of the fibre from the optical axis, the Hermite Gaussian modes can be successively observed. This laser has a variable M2-factor and can therefore be used as an M2-standard in calibration purposes. M2-factors between 1 and 190 are attained with this method.
