Laser Systems and Applications


Course Description

This course builds on the previously acquired knowledge and skills taught in the Introduction to Photonics and the Geometrical Physical Optics courses. Advanced concepts of laser construction and operation will be taught, which includes advanced measurement techniques that depict the various output characteristics for both low-power and high-power lasers. Course participants will be given basic Laser Safety Officer (LSO) training and learn about various laser safety protocols, operating procedures, and equipment used in a Class 4 laser lab environment. Beam profilers, beam splitters, advanced level power meters, spectrometers, and other measurement equipment will be introduced and used in a lab setup. Students will be exposed to the principles and operation of gas lasers (HeNe), ion lasers, semiconductor lasers, fiber-optic lasers, and Nd:YAG lasers. More advanced techniques such as Q-switching, mode-locking, and wave division multiplexing will also be studied on a theoretical and practical level.

Course Length

ONLINE - 6 Months
Practical - 2 full days (optional)

Prerequisite

Introduction to Photonics

Course Learning Outcomes

  • Fully understand and implement laser safety rules, protocols, procedures, and equipment on a LSO-equivalent level
  • Demonstrate a full understanding of OD and NHZ calculation and selection regarding laser safety eyewear for a specific laser type and MPE as well as other laser-safety equipment
  • Understand the differences between various classes of lasers from the perspective of laser safety
