Hello everybody and thank you for all your answers.
Indeed a 700 mw laser line is enough for commun use. But i need a powerfull laser line for an outside installation in a big space that is not dark...
I've try with the 700 mw but it's still not strong enough for the effect we are looking.
I Found laser module that are powerfull then 700mw but when i ask if i can change the original lens (dot) for a line lens, sellers told me that the housing of the laser don't fit with line lens...
Do you know any laser module 638-650 nm stronger than 700mw and have the option to change lens for line ? ( if you have link it will be wonderfull)
Thank you ! Anto
What is your location? Different Countries have different lasers laws, rules and regulations---would guess you are either very young or not in USA or you would be able to spell correctly simple words.
First off red is one of the least visible wavelengths to begin with and an idiotic choice for a high visibility wavelength.
A 200mW 532 green is as bright as a 1W 638 visually for example.
You don't seem to comprehend that what you want does not exist because there is no call or need for it.
Better idea is find another way to do what you want to do.
You keep asking for a line laser that is just you daydreaming/imagining --that exists only in your imagination and nobody else wants or needs for any real reason--is not an available product. You will have to pay to have it created by a laser supplier/designer. You may be able to get something custom made buy a laser manufacturer for the purpose or build one yourself. Is not going to be cheap either way, like the low end mass produced junk laserlands sells. It is going to have to be worth the $s to do or why should anyone bother at all.
Maybe ask these people if they can supply parts to make what you want or if they will make it for you. They offer 638nm up to 6W

Safety is another big concern----if people will see this laser's output you will have to eliminate the possibility of eye damage --anything over 5mW is not eye-safe. Without laser glasses/goggles a 1W and above is a very dangerous laser that can permanently blind someone is less time than the human blink reflex time of 0.25 seconds. If you don't know what you are doing your are a danger to yourself an others --- just an accident looking for a place to happen.
There are laws, rules, and regulations concerning all aspect of lasers and use of same you have to comply with as well.
