Hey Community,

I am new on this forum.

I want to buy a 2W Laser. I have a price range of 300-350$ and the laser should be shipped to germany.

If this price isnt realistic just tell it me because I am new to this forum.

Just as question: What do you guys think of the 1W Artic Spyder III ?

regards,
fischyyy

Hello,

I dont have any laser goggles but I am buying a pair if I get a Laser.
btw. Do you guys know how to turn it off that I receive everytime an email if someone responds to the thread?

regards,
Dennis

A 2W laser is going to be very expensive.
IMHO, the only good 2W builds and dual diode builds.
Pushing 1 diode to 2W without a softstart or anything will give it a short life.
How short will that life be? no one knows. Some diodes can take it better than others.
It may last 3 years or only 3 months.
But 2 diodes making 2W means 1/2 the stress on them and thus double the life.
But then your getting into some higher prices.
If this is your first laser stick with a 1.5W and below.

Thanks to all for your help. You are very nice too me. What do you think about this one I could get for 300$

Take it before another one see this post ;)

I can vouch for Jordan, have several builts from him.

Maybe you can ask him to turn down the current a bit, to reduce the heat and increase the diode´s life time. But as far as I can see, this built is very well heatsinked!

Kiyou, this maybe goes for most of the diodes, but we know that there´re freaks, haven´t heard of many died 2W 445nm yet. And people have them for >6months now.

Yes it is a very common assumption. But I would be more concerned about a diode being pushed to 1.8A that is only delivering 1.8W and under. It is all about the efficiency of the diode. Check this post.

Also keep in mind these display designed diodes are designed to run 50-100X longer than a burner diode that we used to be making portable lasers with. 1000-2000(if that) hours compared to 20,000 hours.

I have not had any issues with the many many 2W units I have built. I have also heard back from Reginak about the Frankenstein(the first 2W portable) and it is still putting out the same power it was the day I built it after many many hours of use. And Aryntha's 2.1W has been run for way over the recommended duty cycle on a constant basis and has many many hours on it as well with no degradation. It seems if the diode is efficient enough to do 2W+ @ 1.8A it will last a good long time.

so i had an idea to build a 2.5A driver.
And run the diode on it with a tec and see how long till it dies.
Any ideas on how long it might run?

It won't run at all. 2.5A is beyond the shutdown current. It just shuts down past 2.1A.:beer:

hmmm. i think once im done building my TEC diode binning tool im going to binn the rest of my projectors.
And what ever diode is the highest im going to set at 2A.
I have always wanted to get one of the g1 or g2 lenses but i have over 50 of the aixiz coated glass lenses.
I just wish i had a tool to measure nm.
That way i could find a laser as close to 473nm as possible.
i know the highest would only be 455nm as the spec sheet says but still a 2W 455nm vs a 2w 445nm there is no comparison.
Any cheap wavelength readers out there? sell diodes each with a efficiency rating along with nm reading would be nice.
