There is no maximum theoretical distance; a laser generates light, and light can go on essentially forever. If you are asking what the maximum distance is at which you could SEE the laser, then that would depend on the power output of the laser. It's not yet technically possible to build a laser that could be seen from another planet, but that day probably isn't too far off.

How far can a laser beam travel?

It depends on what colour it is, the type of laser it is, the output level, the quality of the optics and the media it's travelling through. In a perfect vacuum, they'll travel much longer than through atmosphere. For example, green lasers travel further than red or blue. Class 1 and 2 lasers have an output power level of <5mW. Class 3 can go up to 100mW. See related link.

I want to scare off pigeons and squirrels with a 1mW green laser pen but it doesnt work. Is it the wrong colour or can't these creatures see coloured laser light?

You need a green laser for that & one mw is not enough. I advise atleast a 100mw and sometimes even that is not enough. 80% of the pigeons are gone with even a short bust of green laser light but up to 20% plays difficult.


How much are 100mw laser pens?

Lasers differ in price between manufactures and quality. i have found a 100 mw laser for $16.00. But as a buyer you have to be careful, ordering any laser over 5mw to the U.S is illegal. I do not know how strictly it is enforced. Correction to your reply: Lasers over 5mw are illegal to IMPORT to the USA. 100% legal to purchase in the US
