Ultrafast lasers may be shifting from laboratory equipment to scalable chips.
Researchers at EPFL have developed the first integrated ultrafast laser on a photonic chip that matches the performance of traditional tabletop femtosecond lasers.
A technology that once required complex laboratory setups can now fit on a chip smaller than a match head.
Some of the most important advances in photonics may come not from improving lasers themselves, but from making them manufacturable at semiconductor scale.
Key signals:
• First integrated ultrafast laser reported to match the performance of tabletop femtosecond laser systems
• Generates pulses as short as 147 femtoseconds with pulse energies reaching 1.05 nanojoules
• Uses a Mamyshev oscillator architecture to achieve stable, high-energy pulse generation on-chip
• Wafer-scale fabrication could enable production of more than 1,000 laser devices per manufacturing batch
Why this matters:
Ultrafast lasers power applications ranging from precision manufacturing and spectroscopy to medical diagnostics, communications, and atomic clocks.
Yet their cost, size, and complexity have limited widespread deployment.
Bringing laboratory-class performance onto a chip could make advanced optical capabilities significantly more accessible across multiple industries.
What's changing:
From room-sized laser systems → to mass-producible photonic chips
Integrated photonics is increasingly compressing complex optical systems into semiconductor-scale devices.
This shift could move advanced laser technologies from specialized laboratories into everyday industrial, healthcare, sensing, and navigation applications.
If laboratory-grade lasers become as scalable as microchips, which industry stands to benefit the most?
