CNI can satisfy your 543 DPSS portable needs!

CNI got back to me. ZRaffle your point still stands, 604/607 can't be done, even in their beefier PGL hosts. They will ship GLP to Canada though!

I doubt that it can't be done---it is just because there is no reason to do it--given all the legal restrictions of the market worldwide ---is a business decision on how best to use the resources they have to make money.

Hobbists are probably lucky that CNI will bother to make the low output low cost 720Hz pulsed 589nm as PGL-H modules and used in GLP and PGL hosts--they sell enough of them to make it worth doing and they are the only company doing them---because there is no business $ reason for anyone else to bother.

Consider the 720Hz pulsed 577nm GLP CNI made for the LPF member Dr. Laser in UAE
How many people are going to drop approx $2000+ on a 5mW GLP for amusement/entertainment hobby purposes--essentially playtoy purposes?? So far 1 person--how many more in the next 12 months--maybe 1 or 2?

They probably could make 607nm portables and many other wavelengths also if there was any market or money to be made in doing so but why bother for a few pieces at break even cost/little or no profit when there is no demand, call, or market for $2000+ low output hand held portable lasers even from the enthusiast self amusement/entertainment crowd and there is not going to be one if the past and present are any guide.
Consider what percent of the hand held laser market is laser 301,303, 305 for $10 or less and go from there up the price/product ranges?

Ultra Lasers sells a 10mW CNI 607nm lab laser for $4500 and a 200mW $7000

607nm is not so hard to do, from 2013 paper:
"We report continuous-wave orange laser operation at 607.5 nm of a 8 mm long 0.2at% Pr:LiYF4 single crystal with an improved laser slope efficiency. Using a single InGaN laser diode emitting at ∼444 nm as a pump source, an output power of ∼200 mW was achieved with a threshold absorbed pump power of ∼150 mW and a laser slope efficiency of nearly 42%. M2 factors of 1.40 and 1.28 were measured in the x and y directions, respectively, attesting to the good quality of the output laser beam."

That's a very good point Encap. I remember reading a thread from a few years back where it was saying exactly the same thing you just did, we don't amount to much in CNI's eyes.

probably true in an way but nothing personal--is just that business is business--their purpose is to create business, stay in business/continue, and grow---not go out of business doing interesting things of no business value.

For CNI, lasers are a business not a hobby or playtime thing where it doesn't matter what they do or don't do--look at what CNI says about their business:

< 5mW pointers are what percent of their sales--worldwide?

Not only that ---in the real world see the market for lasers --you have to be in it to win it see: http://www.laserfocusworld.com/articles/print/volume-53/issue-01/features/annual-laser-market-review-forecast-where-have-all-the-lasers-gone.html

Yes. This is by far, the #1 thing that people really need to consider if they're ever wondering about availability, pricing, or just talking to any actual laser manufacturer. Hobbyists are almost of no concern to most of these businesses, and the most reputable ones sometimes are against hobbyists.

If a price is really high, it's because the organizations that want it can pay for it. If a possible diode isn't available, it's because there just isn't enough demand to justify it in the commercial space. The only diode systems that could possibly be manufactured directly for the hobbyist space are a few low power red diodes. The rest are repackaged or openly sold stock from some commercial application.

605-609nm diodes are available, but the current generation requires special cooling. They won't work in a conventional portable laser host, but a more reasonable version is well within the realm of possibility if the demand appears within industry.

CNI is luckily open to hobbyists, but should anybody want to contact another company, please keep all this in mind. In their eyes, you may as well be spam in their email.

Hey guys,

Spoke to CNI. If anyone is interested, they can also provide 622nm. Cost is pretty high, $780 for 5mW in the same module :yh:

The diode alone can cost you around $650.

These are rated 622nm at 5°C and shift 1nm/5°C. At room temperature with the heat generated at threshold of 800mA, I'd excpect it to shift up to 630nm. Not a good option to be in a portable unless there is a TEC.

I also think itll have a fat beam, these diodes are multimode (which is usually a death sentence for beam specs). They usually come in 9mm or c mount packages.

Okay, just though I'd let you know! Also, if anyone wants to do another CNI G.B, it's possible. All handhelds will need to go via Canada however.

If one ever gets going I might be interested in something. The 622nm sounds interesting, it's the closest we might get to a true 'orange' pointer. The 488 and 577 are more interesting, but I could NEVER justify that kind of spending.

You're just that kind of guy, diachi. Always ready to give. :crackup:

How much could it cost from Yellowknife?

Can you confirm if they'd be using any sort of TEC in the 622nm?

If only that 577 was cheaper, I'd gladly go into a GB

Depends on the size and weight of the package of course, but the cheapest tracked option for a 20x10x10cm package weighing 1lb shipped to California is $18.56CAD or $14.90USD - that's uninsured. 6-7 days delivery time.

There's more expensive options available, with tracking and insurance or tracking insurance and faster delivery. Would be up to the recipient really. Of course, if they're insured and properly declared you'd also incur import charges, increasing the price further.

GB sounds good and easy but they are never that easy and without possibility of problems especially when crossing international borders.

Re: CNI Hand helds----If the problem with CNI handhelds to Canada is not the GB/purchasing from CNI but at whose risk/loss if it all goes wrong at any point for whatever reasons is the question.

CNI hand helds are still on the "red list"/ FDA import alert 95-04--
see: https://www.accessdata.fda.gov/cms_ia/importalert_254.html
I don't think it matter who is shipping or from where--if picked up/discovered they are still toast/gone " Districts may detain without physical examination (DWPE) all shipments of the same product as was originally found violative such as laser pointers"--

Remember the GLP 5mW 561nm debacle. see: http://laserpointerforums.com/f55/feeler-cni-561nm-5mw-pointers-94457-19.html
Post # 300 says "CNI forgot to file for an accession for them. basically the pointer equivalent of a variance for them because its a 'new' product from what i've been discussing with them...as well as whatever other paperwork they're supposed to be doing. Customs doesn't have a meter and testing at the gate isn't standard. they have to be logged before they come in, shown that they comply and are labeled correctly, and all that other legal BS."
So back to my question: Who is going to assume the risks and any loss?

Not CNI for sure. CNI itself will not ship any hand helds even GLPs to USA for a reason/real reasons.

Not trying to be especially negative. Just saying may not be as easy as saying CNI will take money for a hand held product order and ship it to Canada.

"properly declared" part may be probematical --see my above comments re 561nm GLP GB
