Laser Science to Photonic Applications (CLEO) 2027

A conference and exhibition for laser and photonics technologies, serving the electronics and advanced manufacturing sectors.

CLEO 2027

CLEO 2027 runs 2–7 May 2027 at the Long Beach Convention & Entertainment Center in Long Beach, California.

What it is

CLEO — the Conference on Lasers and Electro-Optics — is an international conference on laser science and photonics, pairing a week-long technical conference with a two-day exhibition. Optica describes it as a forum for scientific and technical optics that unites the fields of lasers and opto-electronics, covering laser technology from basic research to industry applications.

Who runs it

CLEO is sponsored jointly by three societies: the American Physical Society's Division of Laser Science, the IEEE Photonics Society, and Optica. Optica lists the conference on its events calendar, and the conference itself is run from cleoconference.org, which carries the call for papers, topic categories and committee lists for 2027.
