After working with lasers for over 5 years now and making my own, I'll give you the break down on things.
To achieve a full red beam with a safe output you'll need complete darkness and/or a fog machine. Green lasers would require less output and can be fully visable even in day time because your eyes are able to pick up green better than the available lasers out there. This still doesn't deam lasers as safe. A 5mw green laser can still fuck with your eyes.
Getting the perfect beam in dim lit conditions would require an output very dangerous to other players and is highly unadvised to use in airsoft. I personally would call an official in regards to your laser.
Here is the listing for the quality diodes required to achieve a visable beam in daylight (this means no cheap china knock off shit).
Using an output power of 150mw or higher for a red diode would achieve this, but with that much power being put through the diode can cause blindness to other players. This laser is powerful enough to cut through dark materials such as black electrical tape, and even pop dark baloons.
With green it can be achieved using a 25mw diode, but again really bad for players. This again can cut through dark materials and black electrical tape.
Violet with the 405nm diode will not be visable even with an output of 200mw.
Here is one of my lower powered lasers in day and night conditions

Here is a lesson about your eyes:
- each spectrum of laser requires it's own protective glasses for your saftey and the safty of others. Each pair of glasses can run anywhere from $40-$160
- If a high power laser is pointed at a persons eye even at a distance blindness can occur. This includes a brief flash
- If a laser is pointed at a persons eye, the eye will respond quickly as it recognizes that areas of your eye have been damaged and will compensate the loss of that one area by the surrounding good ones. (this means that because you pointed it at a persons eye and they can see perfectly after doesn't mean you didn't do damage. This is not commonly known)
- Looking directly at the dot can also cause blindness.
- USE SAFETY GOGGLES/GLASSES WHEN MESSING AROUND WITH LASERS IF YOU DONT KNOW WHAT YOU ARE FUCKING WITH~!!!!!
My personal opinion... lasers have no use in airsoft. BBs do not fly in a perfect consistent line to justify a laser. Just use a high lumen flash light and you'll be better off. Sure they can be fun and cool, but not worth fucking around with others. I'd save them for pointing up into the sky, stars, or really tall structures with no windows... like the CN Tower.
Also... pointing a laser in a persons eye can get you kicked out from a game. If someone like me who knows about lasers spots you pointing that shit at other peoples eyes... look forward to a good combat boot to the face. I wouldn't care how many BB's would be shot at me I'd still walk up and kick you in your face. You sure as hell wouldn't want to be on the other end of my high powered lasers... so don't be pointing them at other people. Safty first.
