After 20 years, scientists finally shrink a powerful laser onto a chip
After 20 years, scientists finally shrink a powerful laser onto a chip - Date: - June 4, 2026 - Source: - Ecole Polytechnique Fédérale de Lausanne - Summary: - Researchers at EPFL have developed a chip-scale ultrafast laser that performs on par with traditional tabletop femtosecond lasers. The innovation could make advanced laser technologies far smaller, cheaper, and more accessible for applications ranging from medical diagnostics to atomic clocks. - Share: For decades, ultrafast lasers...
Ultrafast laser shrinks to chip scale, potentially lowering costs for diagnostics and atomic clocks
Ultrafast laser shrinks to chip scale, potentially lowering costs for diagnostics and atomic clocks Stephanie Baum Scientific Editor Robert Egan Associate Editor Ultrafast lasers emit pulses lasting only a few hundred femtoseconds (quadrillionths of a second). These flashes of light power applications from precision micromachining to eye surgery to optical frequency combs, the Nobel Prize-winning technology behind today's most precise optical atomic clocks. Yet despite more than two decades...
