Closest I have found are a 105W no-name one on ebay that looks good but not as good as the Disney ones, the other is the ADJ H20 which doesn't look as good, either. I also doubt Disney has anything from ADJ in their parks! So, These might be some custom jobs. Curious if they might be video...

To use the 555 output to feed a blanking drive circuit I would recommend a method that would lightly load its pin 3, i.e. a digital buffer. Another 555 could be used for this buffer and its output would then feed whatever scan driver circuit you have. I should add that a CMOS inverting buffer...

Thanks Lasermaster1977. I'm reliving some of the same joys that Greg has. Currently not using any laser diodes at the moment. Just using some old HeNe's and a DPSS laser I had laying around. I was just going to use a scanner to test blanking. I'll see if I can put together a circuit that...

Congrats Kevint! Nice image results, too. Many times it is just the simple things. You couldn't use the 555's output directly as a blanking signal since it is 0-15v. Some some down scaling and buffering would be needed to get down to a 0-5v signal. But, I don't recall what you are using for...

Belive me, if anything generated visible light at any practical power level in a transverse discharge, prior to the practical blue laser diode, it would have been on the market. Neon generates exceptionally weak visible pulses in a transverse discharge, so do some very exotic excimers....

I totally agree, I also prefer the retrace line. It adds that natural analog feel to the image which I really enjoy. The main purpose for asking the question is to try to understand where these blanking signals come from and in this case could the 555 time pulse be that source. But all in all,...

"Well you can contribute all you want but that doesn't give you the right to talk down to people." Your duties to moderate there don't give YOU the right to talk down to people. Where in the TOS does it say posters must answer questions with a positive, helpful attitude? You're a moderator, not...

Its difficult to accept when a "greybeard" says no, because, at least in my experience, their information is out of date. I'm not saying that's the case here, but saying no to a question, and then saying "because I've worked with lasers since the 1980's" when they ask why it wont work, does sweet...
