This lab activity, presented by John Chamberlain, is one of four on the topic of interference and diffraction. In this 11-minute video, Chamberlain demonstrates the measurement of both single and double slit diffraction and interference patterns and the calculations required to find the diffraction...

This lab activity, presented by John Chamberlain, is one of four on the topic of interference and diffraction. In this 10-minute video, Chamberlain demonstrates the measurement of the Fraunhofer diffraction of a laser beam passing through a pinhole and the diameter of the airy disk produced as the...

This lab activity, presented by John Chamberlain, is one of four on the topic of interference and diffraction. In this 6-minute video, Chamberlain demonstrates the measurement of diffraction of white light through a diffraction grating and how to calculate the wavelengths of light produced through...

This lab activity, presented by John Chamberlain, demonstrates the measurement of the power and irradiance of a laser beam. In the 10-minute video, Chamberlain introduces the necessary equipment, including a photo detector and power meter, and configurations necessary for the lab. In the first part...

This lab activity, presented by John Chamberlain, demonstrates the determination of the minimum optical density of protective eye equipment needed for working with lasers. In the six-minute video, Chamberlain uses the example helium neon laser to show the process of calculating this optical density...

This lecture, presented by Fred Seeber, discusses the basics of laser hazard classifications as the concept relates to the fundamentals of light and lasers. In 17 minutes, Seeber explains the basics of laser hazard classifications, including the ANSI Z136.1 (2000) Standard, and the different classes...

This lab activity, presented by John Chamberlain, introduces the law of reflection. In this six-minute video, Chamberlain uses a laser and a mirror to demonstrate reflection, and shows how to take readings, measurements, and make the calculations necessary to find the deviation angles and verify the...

This lab activity, presented by John Chamberlain, demonstrates the real images formed by converging lenses. In this 16-minute video, Chamberlain demonstrates the set up required for the activity, including a laser, mirror assemblies, and diverging lens, before showing how lenses can be used to focus...

This lab activity, presented by John Chamberlain, focuses on the measurement of beam diameter and divergence from a laser. In this 14-minute video, Chamberlain demonstrates the set-up for the lab, including how to properly read a micrometer, and taking the necessary micrometer and power readings to...

This lecture, presented by John Souders, covers the basics of metastable states and stimulated emission. Souders begins the lecture on the white board, demonstrating equations and charts related to metastable states and stimulated emission. Discussed are concepts such as mechanics, atomics, and...
