I have also seen a 1 watt blue laser again you can see a weak beam but you really have to look pretty hard.
Laser that you can see the beam.
There are three other factors that affect whether or not a laser beam can be seen the beam s intensity the beam s wavelength and the amount of particulate matter in the air to see a light it needs to actually reach your eye but due to the unidirectional and controlled nature of a laser beam it should theoretically be invisible.
Simple harassment a beam on your skin or clothes is probably not punishable unless it continues or unless it occurs during a critical situation such as driving.

It s great i can still see the laser beam of gren laser pointer at day time.
A dark room is enough or also outdoor after the sunset.
With a green laser you don t need fog to see the beam.
And yes you can try this at home as long as you keep that laser away from everyone s eyes.
Note these are not the cheap ones from the drug store but 200 or so special ordered items.
Lasers are the secret weapon of science they re incredibly powerful super versatile and they can travel across incredible distances but as this simple experiment shows for all that power it s actually possible to trap a laser beam in water.
