I would say that it would probably be fine, you may run into issues as you approach the max blanking speed of each of the lasers. also, if they have different rise time, that could produce a possibly noticeable difference.
on a similar note, My first projector is going to be a dpss blue (i'll upgrade it to RGB later, I plan to cut the learning curve up into chunks). my question is, for one laser, would analog or ttl be better? I can't see where graphics would need dimming, but would the analog look cleaner? btw. this is a 20khz analog. would the ttl be faster? if so would it be better to use ttl?
my inkling is to stick with analog, as I do plan to go rgb in the future, and I figure that would make for fewer programming changes down the line.
