:thanks: I will be needing a green and initially planned to get the osram 520 hence only said I needed a red and blue. It will not be burning any paper so the lower the better - just means a lower filter factor. This bluray diode looks to have a status around here, I will be building a single...

OK Blastertron221, Thanks for the resources. The Blitz driver may be a suitable alternate to the Flexmod as I will be using lower powered lasers as opposed to having engraving set up using higher powered lasers to etch wood etc. Please check my project that I posted a link to on PicEngrave...

I have found this Optical calculator Holo/Or For DTR's rgb kit the lasers do not have beam diameter and quality published. Is beam diameter the same as aperture?

Thanks for the clarification, in any case i'll be needing the lowest power possible for this project, even going through NDs from 100mW. If I were to get pointers, which diodes should I avoid, diode pumped? Basically how can achieve the smallest dot size possible, I assume a longer focal length...

Hi, Are you saying I am simply able to get a lower powered pointer (which are TTL), put it in a module/lens then hook it up to a driver (Like Flexmod, Blitz) and turn it into true analogue? If so that may be much cheaper the sourcing pro-low spec lasers as they seem to be quite the speciality...

Hi guys, I'm new to lasers and the forum. I am currently working on a project which can be followed on the PicEngrave forums, here I am in need of ≤100mW Red and Blue (405nm) lasers that support analogue modulation. I need the lower power to achieve a smaller dot. However such modules are...
