One can purchase a 532nm laser at most major electronics stores, science stores or online. One can purchase 532nm lasers at stores like Best Buy, Amazon, or eBay.
There are several places where you can purchase a green laser pointer, the best place to purchase a green laser pointer would be through eBay or Maplin Electronics, these websites offer 6 in 1 green laser pointers for competitive prices.
You can buy a laser pointer in many places. If you are looking to buy a laster pointer online, you can buy one on Amazon. If you are looking to buy a laser pointer in person, you can buy one at your local Staples or your local Best Buy.
nm is nano-meters. There will be a number preceding the nm. This number indicates how many nano-meters for a full wave length of the laser light. A 532nm is one of the more dangerous levels it can blind a person in a very short amount of time.
yeah.

A laser pointer can be purchased on websites and stores that specialize in technology equipment, such as Best Buy. You can also buy one from an online wholesale website such as Amazon.
There are a lot of places in order for one to buy a 300mW laser pointer. However, it is strongly suggested that one should order from the website Amazon.
I recommend LEDShoppe. It's a 5 mW laser pointer that can be seen a mile away, with a LED light on it as well. Only $3 with free shipping, and they are buy one, get TWO free! The only bad thing is that they ship from Hong Kong, so it will take a week or two to get it but it's worth it for 3 bucks.
I would say to look on eBay or amazon
RadioShack online is a great source if you are looking for a higher end laser pointer. If however you are looking for a cheaper option, Wal Mart and Target online also carry laser pointers.
