NOVAlasers announces new product release!

[wooooooolazer]

Cool, its like the highest power pen style laser there is except for the ebay ones that put out 20mw green and 150mw ir ;D


...lazer... ;D ;D ;D

is a 500mw pump diode the biggest u can squeeze into a pen-style cni pointer? or is it possible with 1W diodes but heat becomes the problem?

We’re glad to see that you’re all enthusiastic about our new product addition!


To clarify the specs:


1. We have changed our testing procedure for all X-Series lasers. Previously we would test them for three 20 second periods and select the median average out of the three and the peak from all three. Now, X-Series laser models 125mW average or less are tested for one 60 second test period from which the average and peak are calculated. Due to their extremely high power the X150 and X175 average and peak stats are taken from a 30 second test period. Most of these units still qualify at their rated power after 60 seconds as well, but we do not guarantee this.


2. We have removed the transverse mode specification from the X-Series product description as we are no longer able to guarantee perfect TEM00 for all units. The X-Series pack a lot of punch in a small housing and some slight mode shifting does occur. Our manufacturer has been giving us grief for returning what they consider functioning units and so short of stock piling these or misleading our customers we have to change our specs. For a visual representation of what is acceptable please see attached image. Mode hopping more severe than this is covered by the warranty and the laser will be replaced.


3. The newly added 150 and 175 models are currently available in the same style housing as our original X-Series. The current draw of these lasers is around the same as the original models and so there is no change in the battery requirement. The pump diode is 500mW. The ridiculously high power that these are capable of is due to improvements in component efficiency.


At NOVA we pride ourselves on our personalized customer service. If there is a particular set of stats that a customer is interested in (a TEM00 requirement, stability, high peak, etc.) please contact us, and we will respond promptly to let you know if what you’re after is available.

The extra testing is definetly a step in the right direction. But i have to ask what kind of price would we be looking at to get a higher powered model with TEM00? Also what kind of stability options would be available?

:-*

Thanks for the clarification Nova.
Chief, other than the extra power its not really a step in the right direction TBH. Basically they're saying these units are overall more unstable and worse at maintaining power. Given the situation, its completely understandable. The OEM says not to leave them on for more than 15 seconds anyway (but of course they have their asses to cover there).

It would be nice to someday see a small unit with better heat dissipation though, more like a WL Evo almost, sold by a good company like Nova in such high powers. A small, stable, portable >200mW greenie sure will be impressive! (hint hint Nova )

is a 500mw pump diode the biggest u can squeeze into a pen-style cni pointer? or is it possible with 1W diodes but heat becomes the problem?

Yep, pretty much. Perhaps if you make everything out of copper and make the case a little thicker and practical for heat dissipation, but that would entail a lot of work! Right now you have a 500mW pump producing a good 1.5W+ of heat in that little uncooled laser body. You get that diode too warm and not only do you get a poor efficiency/quality output, but you shorten the diodes life severly.

Would a crystal set with higher efficiency produce less heat? If thats the case wouldn't these higher power models have a better duty cycle because there using the same 500mw diodes? :-?
