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.
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.
It typically takes around 100 milliwatts (mW) of power from a green laser to pop a balloon due to the focused beam causing enough heat to burst the balloon. However, the specific power needed may vary based on factors such as distance, focus, and balloon material.
Yes, laser beams have one specific wavelength determined by the type of laser used. They also travel in one direction due to the tight focusing of light into a beam through the process of stimulated emission.
A laser beam travels at the speed of light, which is approximately 186,282 miles per second.
A 10 mW laser pen typically has a visible range of up to a few kilometers in optimal conditions. However, the actual distance the beam can travel effectively depends on factors like atmospheric conditions, ambient light, and the presence of obstructions.
Some can travel over 25 miles.
Using lents or using electronic componets or both
yes, black ones only i think
legal just like smoking marijuana :)

Just thought I'd bump this question. An answer would be much appreciated for different strength laser pointers. For Example: 1-5MW >5 - 30MW >30 - 50MW >50 - 100MW >100 - 300MW etc. etc.
There are several places where one can view a video review of a green laser that is 100 mW. Most of these places are video uploading sites; the most popular place to find video reviews of this nature is YouTube.
There are a lot of shops selling lasers on the market. LaserBTB is a very well known shop. Best thing to do is to do some research on forums and pick a shop of your choice.
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.
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
You can buy cheap laser pointers online. Here is the reason: There are thousands and thousands of people searching the web for brighter, more powerful, and cheaper lasers of all colors every single day. The internet can pretty much take all of the credit for allowing this global industry to grow so rapidly. When you can connect laser manufacturers from China and Japan to distributors in the United States, the UK, Canada, and Australia; you can expect loads of people to get their hands on powerful laser pointers. Then you can see more choice for you on the internet! http://www.dinodirect.com/Electronics
yeah, you can mod a lazer pen by taking the lazer from an old cd/dvd burner and replacing it with the one in the pen it can pop baloons and even light cigarettes if you get a powerful one
