Hi guy,
I am mimi, from Golden star laser. In my opinion, laserwave 2W green with small divergence is very good, very sharp beam and bright. For more information, you can check this link http://www.laser-wave.net/green-lase...532nm-2w-5w-v/ . Comparing with CNI, laserwave beam size is smaller than CNI in 10meter and in far distance. Second, modulation frequency is faster, laserwave is 30K modulation, CNI is 10K, but if you need 30K from CNI, you need charge more 15%. Third,laserwave is with lasorb in default, which can be anti-static, lasorb is from Pangolin which is used in laser diode inside. CNI can have, but you need to tell them when you order, if not, they won't add for you, and it will charge more USD8 for lasorb in this.
In project , for example, in water fountain project or some live or concern show, without signal, CNI laser module has beam out, laserwave also has a little,but not so much as CNI.
In color, CNI green color is darker than laserwave, laserwave is light green, CNI dark green. Someone like light green, someone like dark green.
In laser module case, CNI is black, laserwave is silver.
In price, it is nearly the same, I can get very good price from them.
And if you buy red,green, blue, it is better buy from the same company, because PSU they use is from different supplier, sometimes, it has interference especially in big project.
And we can also build the laser for you as customized, I am sure you will love it, I have technician who has around 10 years' experience in building lasers, good alignment and structure. Laser looks simple inside, but from my experience, it is just like looking, it is simple, the same material, but from different people's hand, the taste is different, laser the same. Something looks simple always not simple, one people can do simple thing perfectly is not simple guy, do you agree?
Anyway, I am honest to tell you above as a friend,not for business, you can consider it. Or if you really want the laser diodes, I also can give you good price. My e-mail is: mimi@goldenstarlaser.com , or you can contact Winni, her e-maill is goldenstarwinni@hotmail.com .
