Hi Guys,

?I see a lot of different wavelength lasers, from DVD blue to infrared. What's recommended for cutting gasket paper, along with being able to make grey scale Celtic knots and general fooling around??
As we know, different wavelengths have different effects on different materials so it is impossible to say what is best for general purpose use but, from a safety aspect, my personal preference would be infrared although most use blue (ex-blue ray player).
Last year I cut some gaskets from the G320 stuff using my CO2 laser (http://www.cooperman.talktalk.net/files ... age974.jpg) and they came out well but some other gasket materials I have here would not laser cut at all (it all depends on the gasket material composition).

?I could not find anything bad about flexmod p3 I think I might go with it will I need to add that other thing you suggested also will it work with arts controller with out many problems?
The FlexMod has both analogue and TTL inputs and works in either mode so yes it should work just fine with Art?s controller.
?And what would be a good set up for a test driver/load I am a complete newbie when it comes to electronics?
I am not sure what others do but I used 3 of the high power Luxeon LED?s all connected in parallel with a multi-meter (set to Amps) connected in line with the bank of LED?s.
Just be conservative with setting the current ? we have probably all destroyed more than one laser diode by being too greedy.
Finally a word of warning ? safety goggles, with an OD rating at the wavelength of the laser being used, must be worn at all times the laser is in use or is capable of being brought into use. Children, bystanders, pets, etc must always be kept well clear of the work area and suitably protected from possible laser beam reflections.
