Inexpensive Laser Pointers
My magical journey of making
holograms with a $7.99 laser pointer and
other inexpensive DIY laser diode systems.
Welcome. You are on what was once the hottest web page in the world for holography. Working along with my good friends Steve Michael, and the late Sam Savage, we shook the entire field of lasers and holography by creating holograms with laser pointers and stand-alone DIY laser diode systems. We reported about it right here on this web page that you are reading now. It was such a shift in methodology that many of the 'experts' called it a farce, and said that it couldn't be done (several of them, however, now sell diode lasers for holography). It is still reverberating today throughout the world, and became the #1 selling DIY holography book of all time: Shoebox Holography. Laser diode display holography was not developed in a professional laboratory. It was developed in three basements. Therefore, it was (and remains) the perfect example of trickle up science and technology.
The following web pages contain the original progress reports and photos. It all begins at the end of 1998 with a laser pointer, and concludes at the end of 1999 with a 25mW DIY diode system. Within one year, nothing in holography would ever be the same again. You'll also find laser pointer podcasts, including audio interviews between me, Steve, and Sam, in the HoloTalk Archive.
