Re: Ruby LASER for holography

Wow, very impressive work. How long did the project take and what was the cost of materials?

Re: student looking for laser

Hello, I am a student and recently started learning about holography. I am looking for a reasonably priced laser for DCG and silver halide. If anyone knows of anything, please let me know. Thank you! I have several blue (488nm) Coherent Sapphire laser heads for sale. I have three brand new Coherent...

Re: Decent cheap timed shutter?

I'm planning to build one with a sail servo (i'm using laser diodes without collimating lenses, so beam is quite big) and arduino or ESP8266 microcontroller (so it could be activated remotely). Actually, any servo will go if you want to block just collimated beam, so shutter would be very small. Fi...

SOLD ---- Coherent Compass 532-200 | 250mW+ | 33% Reserve Current

This is a dream laser for holography, as the the unidirectional ring cavity forces SLM operation with a coherence length exceeding 150 meters! This laser is a marvel of engineering. You'll be hard pressed to find another laser operating at such an ultranarrow linewidth for this price. I measured the...

Re: Zilux Photopolymer ...

Curious what the sensitivity is like at 488nm vs 530nm, if you get a chance to test.

I want to ask what their pricing is like, but I see they require you to sign an NDA before even beginning product availability discussions :(

Re: Laser pico projector for making color holograms

Dave, where are you getting these pico projectors? It seems that they are discontinued. Do most other pico projectors work the same way? (Using lasers)
