The Photonic Laser Thruster (PLT) efficiently uses photons as propellant and thus promises to enable innovative space endeavors beyond the reach of propellant-based conventional thrusters. Previously, the proof-of-principle demonstration of PLT used a neodymium-doped yttrium aluminum garnet (Nd:YAG) rod gain medium and resulted in the maximum thrust of $35\mu \mathrm{N}$. This Paper reports 100 times scaling up of PLT using a ytterbium-doped yttrium aluminum garnet (Yb:YAG) thin-disk gain medium and thought first demonstration of propelling and stopping a 0.75 kg mock cube satellite over 2 m in a Class-1000 cleanroom. A thrust stand for PLT was established with a radiation pressure sensor that reduced the thermal convection effect and the configuration complexity. The maximum achieved thrust and specific thrust were $3.36\pm 0.18\mathrm{mN}$ and $7.1\pm 0.6\mathrm{mN}/\mathrm{kW}$, respectively. Further development of PLT using existing high-power laser technologies is projected to increase its specific thrust to $68\pm 10\mathrm{mN}/\mathrm{kW}$, on a par with electric thrusters. The present results conclude that innovative PLT applications, such as propellant-free orbit maneuvering and stationkeeping, are within the reach of existing spacecraft and high-power laser technologies. In addition, the feasibility of PLT-based launchers and landers is discussed.

光子激光推进器（PLT）有效地将光子用作推进剂，因此有望实现创新的太空努力，而这些推进力是基于推进剂的常规推进器所无法企及的。以前，PLT的原理证明是使用掺钕钇铝石榴石（Nd：YAG）棒增益介质，并产生最大推力。$35\mu \mathrm{ñ}$。本文报道了使用掺ped钇铝石榴石（Yb：YAG）薄盘增益介质按比例放大100倍PLT的过程，并认为这是第一个演示，证明它在1000级无尘室中推进并停止了0.75 kg模拟立方体卫星超过2 m的运动。利用辐射压力传感器建立了用于PLT的推力架，该传感器降低了热对流效果并降低了配置复杂性。最大达到推力和比推力为$3.36\pm 0.18\mathrm{牛顿}$ 和 $7.1\pm 0.6\mathrm{牛顿}/\mathrm{千瓦}$， 分别。预计将使用现有的高功率激光技术进一步开发PLT，以将其比推力增加到$68\pm 10\mathrm{牛顿}/\mathrm{千瓦}$，与电动推进器相当。本研究结果得出结论，创新的PLT应用（例如无推进剂的轨道操纵和定位）是现有航天器和高功率激光技术所能及的。此外，还讨论了基于PLT的发射器和着陆器的可行性。
