MIT robot built a working laser cavity in under 30 minutes

A robot has assembled a working tabletop laser cavity in less than 30 minutes, handling the precise alignment usually done manually. Massachusetts Institute of Technology's (MIT's) researchers have developed a reconfigurable robotic optics laboratory that can pick up and position mirrors, lenses and other components, fine-tune them with micron-scale precision and even correct the setup after it is disturbed. According to MIT News, the system successfully assembled a functioning tabletop laser cavity in 50 autonomous manoeuvres within 30 minutes. When researchers deliberately moved components, the robotic system automatically adjusted the setup to maintain the laser's intensity, demonstrating how an autonomous laboratory could continuously monitor and repair its own experiments.A robot takes over the painstaking part of opticsPrecision optics experiments often depend on carefully positioning lasers, mirrors, lenses and cameras.
