Scientists are proposing to build a laser in a crater on the moon to help future lunar missions land safely in the dark and find their way around. This ultra-stable light source could also help us ...

Caltech’s new fiber-like photonic chips achieve record-low visible-light loss, enabling more coherent lasers and next-generation quantum and sensing technologies.

Abstract: We present a deformable ultrafast fiber laser based on a delay-tunable Mach–Zehnder interferometer, which can generate pulses with adjustable durations spanning from 239 fs to 24.51 ps, as ...
