After 20 years, scientists finally shrink a powerful laser onto a chip

Researchers at EPFL have successfully integrated an ultrafast femtosecond laser onto a photonic chip for the first time. This breakthrough uses a Mamyshev oscillator architecture to achieve performance levels previously only possible with large, expensive tabletop systems.
Why it matters
Miniaturizing high-performance lasers could revolutionize fields like telecommunications, precision manufacturing, and medical diagnostics by making advanced optical tools portable and affordable.
For decades, ultrafast lasers have been among the most powerful tools in modern optics. Their pulses last just a few hundred femtoseconds, or quadrillionths of a second, enabling technologies ranging from precision manufacturing and eye surgery to optical frequency combs, the Nobel Prize-winning innovation that powers the world's most accurate optical atomic clocks.
The article is a straightforward report on a scientific breakthrough with no political or social agenda.
