Introduction

摘要

This volume includes the proceedings of the 20th conference on Laser Resonators, Microresonators and Beam Control. Twenty years ago, we started this conference as a one-day meeting. Back in 1998, we had just 18 papers, while this year, the number of announced presentations exceeded 70! In total we had 15 oral sessions, as well as 7 poster presenters. We would certainly like to thank conference co-chair Dr. Lutz Ashke, as well as all members of the Program Committee, for their input in putting together the scientific program, inviting outstanding scientists, and their personal contribution to the success of our meetings. We also would like to thank the first co-chair, Dr. Pierre Galarneau, for advancing the initial success of our meetings, as well as former conference co-chair Dr. Kunihiko Washio for his important contributions.
