Hi,
I'm brand new here but I thought I would post a brief review of two laser pointers that I received from bestlaserpointers.com. I found the site on this forum and knew that it had gotten a few bad reviews, but they were cheap so I decided to stick my toe in the water and make a purchase from them.
The first was the Laser 301, 200 mW, 532 nm, green laser pointer. I received this after just a few days after the purchase. After charging the batteries and turning the laser on, I knew right away that it wasn't 200 mW, but it was definitely more power than a standard pointer. I measured the wavelength to by 532 nm. I measured the power to be 45 mW, but after reflecting off of a dichroic mirror that passes IR, I was left with just 36 mW of green. In other words, 20% of the output power is 1064 nm.
The other laser that I bought was a 500 mW gatling style, 532 nm version. This came a day after I got the 301, even though they were purchased at the same time. The same as above, after charging and turning on the pointer, I knew it wasn't 500 mW and I knew it wasn't 532 nm either. I also noticed that the mode wasn't very good, although after focusing at objects you couldn't really tell. Bad modes though, affect the ability to burn, if that's what you use them for. I measured the wavelength to be 511 nm and the output power to be 130 mW. Unlike the 301 though, there was no IR in the beam.
So much for my first review, as basic as it was. I can't really say that I was disappointed because I had a feeling that the powers were going to be low based on a few comments here, but the prices were right and I got what I paid for. I'm wondering if marking the power up by 4X holds true with their higher power lasers. Do I get 1.3 W from their 5000 mW laser, or will it be less? I guess time will tell.
