I purchased this http://www.extremelasers.com/BLM.htm laser a little over a year ago with no intentions of using it with a laser scanner. A year later and I am now trying to build an RGB projector. On the website under output mode it says CW analog or modulation and then it has (TTL) on the side. I am pretty sure my laser is TTL and not analog modulation, but is there anybody here who can confirm that?
