Gain an understanding of laser systems

From hospitals to bar code scanners, almost all of us interact with lasers in some way.

On this four-week course, you’ll delve into laser systems to understand how they work.

Exploring real-world examples, you’ll gain practical knowledge of laser applications in industry, energy technology, medical fields, and daily life.

Understand the process behind optimising laser performance

You’ll gain a solid introduction to lasers, discovering core concepts such as quantum transitions in atoms, stimulated emission and amplification, and optical beams.

Next, you’ll understand how the designing of advanced materials can help optimise laser performance.

Learn how to prepare a laser system

As you explore the principles of lasers, you’ll learn how to prepare a system to obtain gain.

To further your knowledge, you’ll then learn advanced concepts such as how EM waves propagate in space, laser output spectrum, and the Gaussian beam.

Delve into laser applications

You’ll conclude by looking at the many applications of lasers across various industries.

Through this practical exploration, you’ll understand how we interact with lasers and how this could develop in future.

Collaborating with experts from both Taipei Medical University and National Taipei University of Technology you’ll finish the course with a solid understanding of laser technology.
