It has both analog and TTL. I put another email out to Mimi verifying the total cost for five units shipped to me as being $2481 based on her figures. If that's correct then as I mentioned I would be willing to give up a little on my shipping savings to make this happen. It's not much but it makes it all the sweeter. Also I asked her to clarify the 1500mw that apparently does 1800mw and what can actually be expected. 300mw is not going to make some really huge difference in the end function of this laser but it would be nice anyways. As mentioned elsewhere above I had a CNI head with DHOM driver that was rated at 1500 mW and did a very stable and consistent 1800mw. I bet this is a similar or exact CNI head that I had. What would be nice to know is if this is somehow been modified to run over spec by pushing the driver to run at a higher current. If that's the case then you're probably not going to get the expected 5 or 10 thousand hours they claim but it will probably run beyond the year warranty. I'm just guessing, I have little knowledge of the capabilities of an overdriven DPSS and what can be done with them. I read on Sam's FAQ's that upgrading a pump diode in a DPSS in an attempt to get more output from the crystal set isn't a strategy that's likely to give the desired output. Not for reasons I first may have expected like "burning up" the crystals, but because the actual pump output, although increased in total output, isn't all able to be focused into the crystal set. In fact he indicates there may even be less 808 that goes where it is supposed to go and increasing the pump diode size may actually decrease your output. I realize this is diverging from the point at hand but it just illustrates once again that what often seems to make sense in theory isn't what ends up happening in reality. So, without even increasing the size of the pump diode in these DPSS units there still is clearly a range of output you can get by varying the current through the pump diode. It's doubtful these are designed to run at maximum pump current and are "throttled back" to some predetermined safe operating output that gives a desired power and life expectancy. It seems the obvious thing that would be attempted, if my assumptions are true, would be for a company to purchase a DPSS head unit rated for one output and have a driver built to overdrive the head to get more output and then sell it for more $$$. I'm not going to make a direct accusation of someone who does this sort of stuff but we are all aware of plenty of Far East countries who engage in things more egregious than this. Although it's probably not going to deter me from buying this laser today it wouldn't surprise me in the slightest if what I receive isn't running the way it was intended to and has been modified to squeeze more out of it than it should put out. I wonder if it would be possible to buy one of these, find some serial number on the CNI head, and contact CNI directly to find out what operating parameters it was intended for. Now that I'm thinking of this I will probably attempt to do this sometimes after I receive it.
So, probably sometime in the middle of the morning tomorrow I will have more answers to my questions. I haven't run the numbers yet Jeff but if it turns out that it's only me and you wanting these and instead of a 8% discount we can only get 3% and the final cost with the slightly increased shipping that would be incurred per unit comes to, let's say, $540. Would you still be in for one? PM me with your highest price you'd be willing to pay for one of these and I will see what I can put together.
