ok-
i love all you guys and please, for the love of god, sit back and *REALLY* think about what im about ot say...
What you guys are talking about are "problems" that exist to *NOBODY* on the face of this big blue planet except you laserists who try to perfect things that cant (and dont need to be) perfected. LOL.
Come on guys. are we *really* expending this much time, money, effort, headaches and "research" into 4mm vs. 5mm vs round beam vs. square beam vs. "blueish halo" or "reddish halo" vs. 1.2mrad vs. 1.8mrad vs. who knows what else.
1) 445 vs. 473- NOBODY knows the difference.....except a few of us (us meaning laserists in the know) between the 2.
2) round beam vs. square beam- Almost damn near impossible to notice or see or have *ANY* idea of unless you project a stationary blue beam for an extended period of time and draw EVERYONES attention to it and point it out. In which case, that makes a pretty boring lase show in itself.
3) 3mm vs. 4mm. vs. 5mm or whatever- Again, who notices? who cares? (other than all of us ding dongs here trying to re-invent the wheel)
4) We are *laserists* who are paid (for the most part) to perform shows and provide an entertainment media to an audience. has *ANYONE* in the history of the galaxy and universe and time and space *EVER* have a client or audience member or guest or nightclub or ANYONE say, "Hmmmm....pretty good laser show, but did you see the size of that blue laser beam? it was square and not round!" Or, "Can you believe that crappy laser show we just saw, the white beam had a blue-ish halo around it."
5) the majority of the "issues" of these 445 diodes exist when projecting a stationary non moving beam at large distances. when does this EVER come into play during a laser show?
Sorry, maybe im a "realist" and not a perfectionist. i make shows and equipment to please the people that are going to be watching and paying for my shows. It seems like the only reason why some of this 445 argument comes into play is to try and see who can come up with a magical solution and post it here. It really poses no "real world" achivement to come up with some of the solutions being sought after.
Sure, if it was a simple lens solution to magically make things all better, GREAT. but it obviously isnt going to happen.
get a 445 diode throw a lens in front of it. Clean it up a little bit and do some shows. TRUST ME, the only people who know anything otherwise is people on this forum. And even then, its a few and far between.
Sorry, lol...not degrading anyone or saying your dumb or anything obviously. I just cant for the life of me figure out why this is turning into such a HUGE project. Guys...we have multi-watt blue lasers for the same cost as a night out on the town with a hot chick! LOL. where as before 200mw of blue costs as much as most of our first cars.
then we had problems with the blue dpss "noise" and instabilitys.
Sorry, just my 2 cents. I just did a show for over 2000 people and had the owner literally trying to kiss me afterwards becasue he had so much positive feedback for the display. that was with 2W of 445. and it looked FOOKING beautiful!!!!!!!!
im pleased with the people i am trying to impress. Square 445 beams at 5mm.....Keep em coming baaaaby!!!
Love y'all.....
