Advanced gravitational wave detectors require highly stable, single mode, single frequency and linear polarized laser systems. They have to deliver an output power of ∼200 W and need to provide suitable actuators for further stabilization via fast, low noise feedback control systems. We present such a laser system based on sequential Nd:YVO amplifiers and its integration into a typical laser stabilization environment. We demonstrate robust low noise operation of the stabilized amplifier system at 195 W, which makes it a viable candidate for use in gravitational wave detectors.
先进的引力波探测器需要高度稳定、单模、单频且线性偏振的激光系统。它们必须输出约200瓦的功率，并且需要提供合适的致动器，以便通过快速、低噪声的反馈控制系统实现进一步稳定。我们展示了一种基于连续Nd:YVO放大器的激光系统及其在典型激光稳定环境中的集成。我们证明了该稳定放大器系统在195瓦功率下能够稳健地低噪声运行，这使其成为引力波探测器中一个可行的候选方案。
