Video Short Courses on Lasers and Fiber Optics
With Professor
Shaoul “Ziggy”Ezekiel
Two Exciting courses available:
Learn from one of the most exciting educators around who makes complex subjects
understandable.
These video courses are designed for engineers, scientists,
medical personnel, managers, and others who work with lasers or fiber optics,
or who anticipate working with lasers or fiber optics, yet have little or no
background in laser or fiber optic basics. They focus on fundamentals and emphasize a physical
intuitive interpretation of laser and fiber optic phenomena and their
applications. Because Professor
Ezekiel keeps mathematics to a minimum, topics are easily understood, even by
someone without a strong technical background. However, extensive references are given should you wish to
pursue a more in-depth understanding of the subjects.
Understanding Lasers and Their Applications and
Understanding Lasers & Fiber Optics are professionally produced on
high-quality color video masters.
Multiple cameras capture in close-up the demonstrations and graphic
illustrations, allowing you to see various laser and fiber optic phenomena in
great detail.
Understanding Lasers and Their
Applications
- New easy to follow 6-hour video course
- Graphic demonstrations of basic phenomena
- For all who need to know about lasers
 Lasers are essential to an incredibly large number
of applications. Today, they are
used in bar code readers, compact discs, medicine, communications, sensors,
materials processing, computer printers, data processing, 3D-imaging,
spectroscopy, navigation, non-destructive testing, chemical processing, color
copiers, laser “shows,” and the military. There is hardly a field untouched by
the laser. But what, exactly, is so unique about lasers that makes them so
effective?
In his new video course
“Understanding Lasers and Their Applications, Professor
Shaoul “Ziggy” Ezekiel, MIT Professor in the Department of
Electrical Engineering and Computer Science and Department of Aeronautics and
Astronautics uses simple language to explain the basic characteristics of
lasers.
 With specially prepared demonstrations and numerous
graphic illustrations, he helps you visualize and understand the basic phenomena
that govern the behavior of lasers and their applications.
