Open Cavity HeNe Laser Experiments
University of Wisconsin – River Falls, July 12-14, 2019, 4 setups (8 participants)
Participants do not need to bring anything besides themselves, though they may want to bring some means of taking notes about their procedures, and a way to save any data files.
Estimated Cost: Ealing sells a basic open-cavity HeNe laser system for $3500; Leybold has a very sophisticated system for about $39,000; a tube, power supply, and mirrors (but not mounts) can be purchased from LASOS for approximately $2500; and reliable used equipment can be found (Sam Goldwasser's "SamsLaserFAQ", for example) for much less, though the selection may be limited.
Host and Mentor:
Lowell McCann is a professor at the University of Wisconsin – River Falls, where he teaches a wide variety of physics courses including Advanced Lab and Optics. He is biased toward experimental physics, and in particular toward undergraduate experiments that require students to build their setups starting with an empty table.
