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.

Update-

This has really become more of a feeler thread with day by day updates on the negotiation between two companies. I suppose that's fine however. Once I get a better idea of what people are looking for and a final price on those units we may do well to re-post a new thread altogether. Just a thought for now.

Ok, here's where things are at right now. Mierelight has responded with a new offer that's not quite as good as Goldenstar 's IMO, I'll let you decide. They came back with a final cost of $490 shipped on the original laser discussed above. I couldn't get Bishan to comment on the actual power output like Mimi gave. That part of the question was left unanswered twice now. Also, the original laser was analog only as far as I can tell, at least that's what's advertised. Bishan added a link to an eBay ad of what appear to be a similar laser to the original one in question that was both TTL and analog but didn't say this was the laser he was selling. He apparently was showing me how much he was coming off his price by pointing me to the price of a 1500mw 532 (I'm not linking to that eBay ad now to avoid muddying the water) I've asked for clarification again but it seems the more questions I ask the less response I get back from him. Mimi on the other hand is quite good about meticulously answering my questions. To be honest I just like dealing with her more because of this. I feel lke she is more attentive and accurate. Her final price on 5 of the CNI units has even come down more due to shipping calculations. It's at $487.20 per unit now. I have included a short excerpt from our last correspondence.

. Assuming the shipping weight is accurate at 4kg per unit we would be looking at approximately $53 for the first and an additional $32 added per unit. For 5 units my calculations come to $181 total shipping.
At a 8% discount on 5-9 units five should cost $2300 (500-8%=460*5). This totals right around $2481 for 5 units of the CNI 1500mw 532 unit advertised.
If you buy 5pcs, we will make it as 21KG, and then total shipping cost is USD136.5, you can save shipping cost, because above 21KG, we will make it as 21KG to save money.
So if 5pcs, total cost is : USD460*5+US136=USD2436 , if you pay by paypal, it is 4% handle fee.



Additionally, Mimi has offered a 635nm 1300mw TTL/analog for a base price of $460 that should have the same discount applied. Although I am not 100% certain she will give the 8% discount on it if at least 4 other units are purchased I feel pretty confident she will. That would bring the base cost down to $423 plus change on the 635.

At this point I believe Goldenstar has the better offerings, prices, and customer service. It appears I've got one other party with some pretty solid interest in making a purchase soon on one or two units, I'm most likely in for two myself. I was thinking of doing a new post with a different format altogether to see if more attention could be attracted. Something with the title like "Goldenstar GB: labbies as low as 532 1.8w $460 / 635 1.3w $423 and more..."

Oh yeah, almost forgot....a little research done over at PL seems to reveal Goldenstar is a reputable distributor others have bought from without issue. Haven't found anything outright negative yet. Going to do a little more digging today now that I'm off work for a few days.

I'm off duty for a week so I have some time to devote to this now. Personally I'd like to place an order by Friday if possible but I'm willing to drag my feet if others need to.

Suggestions or thought welcome, particularly on starting a new thread.

Thanks everyone!

I am down for two units for sure and in no hurry so take all the time you need :D

You could start a new thread with 532/650/638 in the title :whistle: or just change this title.

I'm pretty sure that I would take on a 1.5W 532nm laser in ANAlog version. (1.8W)
But I have one condition. I need this laser at the latest by 01.06.2014 - 06.06.2014

To be honest. Today I had to buy the same unit on ebay Mierelight for 768 $ with shipping. I have to add to that about 23% Vat so my costs will rise even more.

However, I read the posts on FL and here. I would gladly decided. It's for me really big savings. Besides It is goldenstarlaser and also CNI module is best for me. :)

But As I mentioned. The deadline to reach a laser to me would have to be in the range 01-06 June. (The latest is June 16). So it all depends on when gathered together a sufficient number of buyers for these lasers.

I would probably place an order early next week. Your timeframe seems doable. There is one issue, you're in Poland. Part of the savings I'm getting, and thus the prices you've seen me quote, are from combined shipping to one place. I can ask Mimi what the cost would be to mail directly to you. I know it will still be cheaper than buying direct by your self. We would just need to figure out a few issues with having them mail directly to you. One would be that I couldn't front the money for the laser on your behalf for obvious reasons. Yours would need to be paid in full up front. Second, on a situation like this I would want you to pay them directly. Basically I would be asking if I could get you the discounts we are getting here because you are buying "with me" and not independently. Sort of like tacking you on extra as one more, bought seperately but as a part of our group. Does that make sense?

I will ask Mimi tonight and see what she says. Remember, your shipping would be the same as if you bought it direct by yourself. You'd just be getting the 8% discount. I think it's around $53 shipping if purchased one by one direct,

This is good news. If you could ask would be grateful. It's also important for you because you have someone who noticed this "deal" thanks to you.
If possible ask also what it will be shipping? by DHL or what?





!:thanks:
