LET 210 Laser and Optical Systems and Applications

5 credits
This course will provide students with a fundamental overview and understanding of the most common types of laser and optical sources and their associated applications. Laser assembly, alignment, and diagnostics will form the foundation of this course. The student will develop a working knowledge of He-Ne, CO2, diode, Nd:YAG, Ar+, and fiber laser systems. LED lighting and Photodiode detection systems will also be covered. Laboratory and hands on learning are emphasized. Safety standards and procedures will be emphasized throughout the course to thoroughly familiarize the student with the proper photonics work environment. 

Prerequisites: LET 201 

Student Outcomes/Competencies:
Upon successful completion of this course students will be able to:

  • Determine focused beam spot size and location
  • Measure laser power output (peak and average)
  • Measure and calculate power density
  • Use an IR alignment scope
  • Assemble and characterize CW, pulsed, and Q-switched laser sources
  • Generate 2nd  harmonic (e.g. use KTP) for different laser formats demonstrating peak-power benefits
  • Describe basic optical harmonic conversion and Energy and Momentum Conservation
  • Evaluate the use and appropriateness of lasers for common engineering metrology applications
  • Calculate optical beam propagation through free space and fibers
  • Describe safety procedures to be followed when working with lasers and optics
  • Describe and demonstrate fiber coupling and operation and apply the principles to optimize fiber coupling efficiency
  • Specify the proper laser sources for common applications 
  • Describe the safety precautions and lab protective gear for laser systems: Class 1, 2, 3a, 3b, and 4
  • Set up and align Michelson interferometers and define optical interference and its basic uses in industry
  • Describe, measure, and apply correctly radiometric and luminous flux definitions and measurments
