The lasers look nice and if indeed new should last about forever for a home holographer. Unless defective these should also be SLM. Be aware the digital controller boxes you may see on e Bay do NOT power the laser heads; they are merley a computer interface to control the analog controller box with a PC. You still need the analog controller to power these as well as a DC supply. See sam's Laser FAQ fior all the details. Phil 142laser

Exactly correct, these require an analogue controller to run. I have the Vicor DC power supplies for the analogue controller if you want a fully stock Coherent system.

Please PM me.
Thanks

I'm in the UK (Ebay.co.uk) and there aren't any listed there. However, i've done a search on Ebay.com and all I can see are 'digital' controllers which will not work without an analogue controller, see Phil's (142laser) post above.

These are not trash, they are not failed units, they are not scrap. These are legitimate systems which came from a local company.

OK so they are in spec and you will accept a return if they say lase on two lines or are not pure SLM right? Both of these defects CAN occur but are quite rare and the chance of two lasers having these isues are almost impossible unless two were rejected out of say 200. I bet they are 100% perfect.
