Semarang – Universitas Diponegoro’s UNDIP Global Classroom (UGC) once again brought in an international academic by hosting a guest lecture titled “Modern Optics” with the theme “Basic Principles of Lasers and Their Applications.” The event featured Assoc. Prof. Dr. Raja Kamarulzaman Raja Ibrahim from Universiti Teknologi Malaysia (UTM) as the keynote speaker and was held virtually on Monday, May 25, 2026.
This initiative is part of Universitas Diponegoro’s commitment to broadening students’ global horizons through academic interaction with international experts. Through this lecture, participants gained insights into the fundamental concepts of lasers, laser beam characteristics, and their various applications across the fields of science, technology, industry, and medicine.
In his presentation, Assoc. Prof. Dr. Raja Kamarulzaman Raja Ibrahim explained the fundamental principles of lasers, including stimulated emission processes, population inversion conditions, and the role of optical resonators in producing coherent laser light. Furthermore, participants were introduced to developments in modern laser technology widely used in various fields, ranging from precision manufacturing, optical communications, and remote sensing, to medical applications.
The lecture was highly interactive, featuring a discussion and Q&A session that engaged students from the Undergraduate Physics Program at Universitas Diponegoro. The participants’ enthusiasm was evident from the numerous questions raised regarding developments in laser research and opportunities for its utilization in multidisciplinary research.
Through this activity, students not only gained a theoretical understanding of modern optics but also caught a glimpse of laser technology research and innovation trends at the international level. This event is expected to inspire students to become more active in research, particularly in the rapidly evolving fields of optics, photonics, and laser technology.
