New items at NOVAlasers!

I would like the new laser better if it was powered by some other battery. My Aquarius consumes the CR2 in very little time. Anyway, I am petty sure I can get these in the CNI GB's if a laser with a CR2 is really wanted. -Glenn

Yes yes yes!!!!!

 

[sandidgepatrick]

Calm down luke....lol yah i would be interested in GB too...

 

[kevinmassey]

i would be interested if any of them could get below 300$

Remember that in the laser market you get what you pay for.
For someone on a budget, Optotronics pens are good for the price/power ratio, but the quality of the newwish style pens is inferior to these CNI built units.

Even directly from CNI, a 150mW pen will cost you more than $200.
Why? Because you are paying for higher quality components.
The $400 price tag at NOVA is the markup you get when purchasing from a distributor. The extra $$ pays for quality control and customer support.
In my opinion, the price is fair. You will not find a high quality, pre-tested and metered 150-250mW pointer for a better price from any other retailer.

Nice explanation, +1.

It's about time that NOVAlasers updated its website.

Cool! Finnaly! Ever since I first got into lasers Nova's website has seemed deserted!

:thinking: uhmmmmmmm ....... i'm wondering about how they got 275mW of green (I can only suppose that they are speaking about 275mW IR filtered, cause in all the description i can't see anywhere the words "IR filtered" ..... ) off from a bonded crystal set, with an 1W 808nm diode , when the actual better efficency for these crystals is around 23/25% .....

Let me clarify what i mean ..... i'm NOT saying that the thing is impossible ..... i have, in fact, a cavity where i've mounted a 3W 808nm with FAC diode, and in a week of alignment i've got, after an IR filter and for short periods (i don't want to fry it, after all ), peaks of 770mW, decreasing around 650mW in 10 seconds, and staying stable for a pair of minutes ..... this mean an efficency higher than 25%, after all ..... but it took me a week just for find a decent alignment, and i don't think it's so easy to do the same thing with 12mm modules (mine is a lab-style cavity) .....

..... except, maybe, the only 2 other possibilities that comes me in mind ..... or that 1W808nm diode is overdrived around 1,5W, and in this case i'm wondering how much of those "3000/5000 hours expected life" declared you can get for real ..... or there's no IR filters on that unit, and in this case i'm curious to see it measured with a filter .....

(I know, i know, i'm a damn curious one ..... but what i have to do, about this ? ..... i'm curious, it's in my nature )

NOVA states on the front page that all lasers are IR filtered. Also, the specs claim 99.5% IR filtration. I know CNI (the manufacturer of the laser in question) installs an IR filter in all their visible wavelength DPSS lasers.

These lasers are a bit bigger than the average pen style. The module itself is about 16mm in diameter. This provides a little more mass for heat-sinking and more room for components.

The specs claim a 1W diode, in which case the efficiency would have to be really high to achieve, but I don't think they are over-driven to achieve output. If that were the case, the laser would heat up so quickly that it would be useless. I think it is more likely a 1.2W diode like is used in the lower power portable lasers manufactured by CNI.

I too am curious how they achieved such high power from a tiny pointer, but I believe it, as NOVA is an honest company and I have had good dealings with them in the past.
Anyway, CNI has produced some very high power portables for forum members... like davidgdg's >100mW 473nm (rated for 50mW), quadcam's 40mW 593.5nm pen, and my own >650mW PGL (rated for 400mW), so I'm sure that it is doable.

Perhaps I will talk to NOVA about getting a review unit to borrow... That may be fun.

It's been a long time since I've heard anything from NOVA, but they have just added some new items and redesigned their website.

They now offer a 275mW pen, comparable to the Dragonlasers' "Aurora" and the "Alpha" is now available up to 225mW.

And the best part-- NOVA still has the best distributor prices on CNI products!

It's worth a look.

The price cannot be the best, and this model at ¤¤200mW-250mW Green Lasers Yamakata Series,Powerful Green Laser Pointer 200mW-250mW $498.99,Freak Lasers can be a best distributor pricing. $499, Vs $699, the same cni model at DL.

The 5mw blue laser pen I got from them came with a power test verification (9.09mW) and two labels with "cnilaser.com" on them. Obviously standard cni laser pen.

I just wonder if cni gives them similar dealers' preferred pricing and why such much profit margin in laserglow or DR can still make them 'recommendable'.
