I direct this question to you because of your working relationship with CNI.CNI states on their site that one of the wavelengths is 556nm. As you probably know that is one nm away from peak visual sensitivity. Pointers would be about 25% brighter than 532nm pointers.I was wondering if they would make pointers that operate at that nm. What do you think?

Thanks
 
I personally think that they're only gas based lasers but I could entirely be wrong... /ubbthreads/images/graemlins/smile.gif I'd like to know the answer as well!
 
Isn't 556nm the wavelength of the yellow pointers that are showing up?

Nah, the yellow lasers (at least the ones CNI make) are 593.5nm. CNI does make 556nm lasers with >100mW output, but none of them are pointers...yet. /ubbthreads/images/graemlins/smile.gif
 
Comozo,

I have never discussed this product with CNI, but my impression is that for the right price, they will attempt to make anything. In other words, they obviously have a DPSS method to produce a 556nm beam. As far as I know, it's never been built into the portable housing, but I'm pretty sure they would give it a try if you offered them enough money. Perhaps if they received numerous emails about this, they would make these available. I'm really curious what the technical details of this laser are. It probably involves a process more complicated and less efficient than a 532nm DPSS laser, thereby making very high power levels unattainable, especially within the limitations of a portable laser. I don't really know though. I wish I knew more.

One thing I think CNI is realizing is that there is a high demand for portable lasers. I think they're in the process of increasing their portable laser division. Hence the new blue and yellow models, and the more powerful green models. They have increased their DPSS manufacturing precision, and will now guarantee >160mW to anyone who asks (and pays). I'm guessing we're going to see them offer a >300mW handheld 532nm unit within a year or so. I'm sure other wavelengths will also be introduced, and the other colors they currently offer will get more powerful as well. CNI has the high-power portable DPSS laser market to themselves right now. They also seem to have a corner on the portable DPSS market in colors other than green. I don't think that will last long. I bet we see other manufacturers offering products like this. Well, I've strayed off topic, but there are my predictions for 2005-2007.
 
>300mW?! Jeeze, when will it stop?!

How much power do you think it is possible to harness in a handheld unit? As you know I was willing to pay more for guaranteeing me get a 180mW+ unit but CNI never replied to me lol.

I might get involved with buying batches of lasers myself actually /ubbthreads/images/graemlins/smirk.gif
 
They really do prefer bulk orders...here's a tip send to the 'other' address on their contact details.
 
Some info copied from CNI.
Wavelength(nm)& output
266 1mw
355 1mw
457 1-10mw
473 1-50 mw
501 1-5mw
532 1-5000mw
556 10-50mw
593 New mw?
671 1-250mw

There are other longer wavelengths. I believe CNI is the only maker of yellow/orange pointers being sold.
