We developed an ultra-stable laser system at 946 nm for the interrogation of our multi-ion clock based on Indium ions. The demonstrated instability of 1.1x10-16 at 1 s ranks among the best instabilities achieved worldwide with ultra-stable lasers at room temperature. In addition, all key components...
