This manual contains thirty-four experiments that have been developed by teachers and thoroughly tested in the classroom. These experiments focus on the use, development, and theory behind an He-Ne laser. Students are guided through progressively more difficult levels of understanding of light physics and optics. This is excellent program material for the novice, or for more advanced students refreshing their understanding of the material.

Besides guiding the student through 35 exercises in optics, the booklet also explains theory of laser operation, the construction of a laser and laser safety.

• Measure the wavelength of light using the techniques of Young, Michelson and Lloyd
• Construct optical levers to detect and measure very small movements that are almost imperceptible to the human eye
• Test a lens for defects, collimate light and check vision
• Capture light in an arcing water jet or a glass fiber and investigate fiber optics phenomena
• View a hologram, observe interference rings and measure the diffraction patterns with a ruler
• Determine the index of refraction of a liquid or transparent solid by measuring the bend in the intense laser beam as it enters or leaves the material
• Investigate reflection, refraction and critical angle
• Study characteristics of light: wavelength, interference, diffraction and polarization
