Introduction
An introduction to the process, including how it all began.

First Test Shots
First test shots including using batteries as a power source for the laser pointer.

Multiple Color Holography
Creating a multi-color reflection hologram using a $7.99 laser pointer.

Alternate Matierals
First test using materials other than AGFA for creating these holograms. Great results with BB-Plates from Germany.

Larger Format Holograms
A successful 8 x 10-inch hologram using a $7.99 laser pointer. This hologram exhibits depth going back to 8 inches.

First Workshop Hologram
Students from the New York area make their own laser pointer holograms at my studio.

Necklace Hologram
A beautiful hologram using an overhead reference beam with the $7.99 laser pointer.

AC/DC Power
Test shot using an inexpensive AC/DC power supply to eliminate the need to buy batteries for the pointer.

Solar Power
Hologram created using the $7.99 laser pointer getting power from a photovoltaic cell located outside my studio window.

10mW Tests
Moving up in power from the laser pointer to a 10mW diode module.

Shoebox Holography System
A new system I've developed to create holograms. The entire system fits into the area the size of a shoebox. Great for teachers, students, science fairs, demo's, etc.

Hologram Portraits
Learn how to inexpensively do hologram portraits of people for fun and profit.

15mW Diode Test
A successful hologram created with a higher-powered, inexpensive, 15mW laser diode module.

35mW Diode Test
The most beautiful hologram yet, using a 35mW laser diode module. This inexpensive laser diode module replaces a $7,000 HeNe laser!

Home Built 25mW Laser
Success in building an ultra-stable, 25mW diode Laser assembly -- with custom-designed electronics for great holographic recording.
