LET 201 Fundamentals of Light and Lasers

6 credits
This course will provide students with a basic understanding of light and its integration into opto-electronic devices (e.g. lasers). Safety standards and procedures will be emphasized throughout the course to thoroughly familiarize the student with the proper photonics work environment. This course is built upon a comprehensive laboratory program that develops a practical intuition to complement conceptual understanding. Application of optical principles to the analysis and characterization of laser systems is emphasized.

Prerequisites: ELEC 110 , ELEC 120 , and MATH 098  or MATH 099  (or placement scores for any MATH& course), or instructor permission

Corequisites: PHYS& 114  

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

  • Define the wide variety of employment opportunities available to Opto-electronic Technicians
  • Define these properties of light: wavelength, frequency, speed, amplitude, energy, phase, coherence, and polarization
  • Describe the electromagnetic spectrum and diagram the main optical regions
  • Describe safety procedures to be followed when working with lasers and optics
  • Demonstrate how to set up optical systems involving optical components, optical benches, and optical diagnostic equipment
  • Demonstrate how to handle, store, clean, and characterize optical components
  • Distinguish between laser and non-laser types of light sources and identify their characteristics
  • Describe the following basic laser classifications based on the appropriate hazards: Class 1, 2, 3a, 3b, and 4
  • Practice and communicate laser safety and describe eye damage related to wavelength (different wavelength regimes for Cornea, Lens and Retinal damage) and exposure times
  • Describe optical systems in terms of fundamental physical optics: waves, rays, reflection, refraction, dispersion, critical angle, thin and thick lenses, F-number, and numerical aperture
  • Describe optical phenomena and systems in terms of fundamental physical optics: Huygen’s principle, constructive & destructive interference, diffraction patterns, Brewsters angle, and polarizers
  • Describe waveguide TIR Principles and their importance in current technologies 
  • Describe and characterize the output of laser light in terms of wavelength, optical waist, power, irradiance, Rayleigh range, and divergence
