Exhilarated by my 15 Minutes of Fame thanks to my junk lasers having been featured in the Chicago Reader, it seems like a good idea to elaborate on my collection.

The exhibit is arranged in ascending order of the lasers I have acquired or worked with over the years in the field of holography. However I have not had the time to finish these exhibits, dear viewer. But the other 3 museums do have some very cool stuff!

Metrologic ML-820,  2 mW @ 633 nm He-Ne
Melles Griot LHP-171,  7 mW @ 633 nm He-Ne
Spectra-Physics 120a,   5mW @ 633 nm He-Ne

Still In Use:
Lumonics/JK Lasers HLS-2 Ruby, 1 Joule @ 694 nm
Coherent Compass 315-M 100 mW @ 532 nm DPSS Nd:YAG
Uniphase 1145P, 20 mW @ 633nm He-Ne
Melles Griot BLD-605, 400 mW @ 458 nm DPSS Vanadate
Lasos, 200 mW @ 640 nm DPSS

Lake Forest College Lasers
Apollo Ruby, 50 mJ @ 694 Ruby
Coherent CR-2, 2 W @ Argon wavelengths
Spectra-Physics 166, 5 W @ Argon wavelengths
Coherent 1 W @ Krypton wavlengths (The LaserSmith's laser)
Spectra-Physics 120, 5 mW @ 633 nm He-Ne
Spectra-Physics 124a, 15 mW @ 633 nm He-Ne
Spectra-Physics 125, 50 mW @ 633 nm He-Ne
Spectra-Physics 125a, 50 mW @ 633 nm He-Ne


Real museums send their archaeologists and paleontologists out into the field to dig for artifacts buried for centuries or millennia or whatever the word is for millions of years.  Here are some “excavations” that this museum has made, in pdf Slide Show format.

It would be hard to find any holographer's Spectra-Physics Model 125 Helium-Neon laser that didn't pass through the doors of 4829 Platt Road, Ann Arbor, Michigan, USA at one time or another for a shot of gas and a thorough tweak at the hands of a man who was there at the dawn of the lasers and holography age, Don Gillespie. He knows these beasts inside and out, as he was the one who designed any serious competition to the fabled S-P Model 120 series He-Ne line up of yore.

Here is a photo gallery of the contents of the shop as taken by yours truly when Hans Bjelkhagen and I were visiting the Detroit area for Hans's beloved Fairlane Fest in June of 2014. A no particular order walk around of 7 or 8 decades of laser and radio tubes and other beloved tinkerer's what-nots. All that's missing is Don describing what you're seeing.
