Greetings from the General chair

Dear colleagues,

We are happy to announce that the 12th Asia-Pacific Laser Symposium (APLS 2023) will take place during September 4-7, 2023 at Hakodate, Hokkaido, Japan.

APLS was initiated in 1998 and has been held bi-annually in Korea, China, and Japan to provide an international forum for the recent progress of lasers and photon sources covering the basic science to industrial applications.

APLS 2023 will be organized by the Laser Society of Japan and co-organized by the Optical Society of Korea, and Institute of Physics, Chinese Academy of Sciences.

As always, a key aspect of international symposium is the chance to network with colleagues from around the world. We welcome you to actively participate in all aspects of the symposium and hope that you will benefit from these interactions.

We hope that you will enjoy your time at APLS 2023 and this opportunity to explore the rest of Hakodate, one of the most popular tourist destinations in Hokkaido.

Students are especially welcome to attend the symposium and help shape the future laser research community in the Asia-Pacific region.
