A team led by Professor Tobias J. Kippenberg at École Polytechnique Fédérale de Lausanne (EPFL) has achieved a significant milestone in ultrafast laser technology by integrating it onto a photonic chip. This development allows for the production of lasers that emit pulses lasting just 147 femtoseconds while delivering 1.05 nanojoules of energy. The innovative design employs a Mamyshev oscillator, which enhances performance in the compact environment of photonic chips, enabling the laser to fit within a space smaller than a match head. This breakthrough could lead to the mass production of over 1,000 laser cavities at once, resulting in lower costs for ultrafast lasers used in diagnostics, sensing, and atomic clock technologies. The implications of this technology are vast, potentially enabling portable tools for environmental monitoring and medical diagnostics, as well as advancing the development of compact optical atomic clocks for communication and navigation purposes.
