Green Laser

With just write the word "laser pointer" in the Google search engine will find hundreds of companies out there in laser pointer. Some are very attractive sites with very high prices. Some laser pointers offer the same features and power, but are much cheaper. It's all very confusing, especially when you do not understand what all the terms. You are about to spend a good amount of money on a laser pointer, the least you should do research before choosing the appropriate laser and right company for your needs.

The first thing you notice about high power green laser pointers is that they always are classified by power. This is the number with "MW" in the end. mW mean milli-watts and is 1 / 1000 of a watt, that is, 1000mW is 1W. You can also see another number associated with green laser pointers. This number has "NM" at the end. This means nano-meters and is used to measure wavelength. You really not find in this issue too as all green laser pointer has a wavelength of 532nm. Rather, when you see 532nm, should automatically think of the color green.

Now, lets focus on power. This is probably the most important factor, because the more buying power, the more money you spent. Yes, power is expensive! One must ask, what are you buying this laser pointer? I think this can be categories in 3 types of lasers.

The first type, you're looking to buy something for everyday use. You are a master, teacher, or someone who is always making presentations in large groups. Seeking to use green laser pointer as a "pointer". Well, I can make the decision for now. Get a 5mW green laser pointer. While you could buy something more powerful, I suggest getting something more than 20mW saying if all you going to do. 5mW is for the small class that points, 20mw is for long distance pointing in an auditorium. Now, I'm talking real laser pointers, ie, do not buy on eBay or any auction site. His production is often false advertising. If you 5mW buys it will probably end with a 1.2 MW of green laser. You can search for "Skylasers" in Google, they are a reputable company well.

Now the second type is looking for a green laser pointer beam visible. First question, are you looking to burn or melt any thing with him? If the answer is no, stick with a green laser pointer from 20mW to 80mW. During the day, these lasers have a very bright end point (not the laser beam is visible). Realize that you will not find a laser pointer with a beam visible during the day. At night, however, 20-80mw green laser is very bright! Yes, incredibly bright! This is where I wonder, how it intends to spend? The more power you buy, the brighter the laser pointer. In a personal note, I would recommend A 40 - 60mW green laser pointer if all you want is a light beam. The 20mW is still a bit dark for me. 40mW to 60mW laser pointers green to go around $ 100 - $ 150. If you have the money, go for the 80mW, you will notice the difference in brightness. I 40mW - 60mW is quite bright though.

If you're looking to burn and melt with this laser, you need something above 100 mW. Want to see the laser pointer in action? Simple, go to youtube and search "lasers". You will find several pointers green laser lighting companies cigarettes, blowing up balloons, etc. There are some videos very cool there. The question now is, what do you want to burn? Again, the more power you have, the faster your laser will burn and melt. You can buy green laser pointers with more than 500MW in these days can cost you a fortune. It really depends on you as to how much you spend. If combustion is your thing, look around for reputable companies and compare prices. Buy something you're comfortable with spending.

There are several laser pointer forums out there that can be very resourceful for you. Stick with www.laserpointerforums.com target = "_blank">, target = "_blank"> www.photonlexicon, and www.candlepoweredforums.com target = "_blank">. These forums are a good following and members are usually very eager to answer your questions. I suggest staying away from www.lasercommunity.com target = "_blank">, this forum is very well controlled and administered by a laser company. They do not allow members to talk about other companies with laser ...
