Focusable 200mw Blue 445nm Laser

AMN · Mar 20, 2011

Hi everybody, I've been looking for a Focusable 200mw Blue laser with a wavelength of 445nm, not 405nm, because I don't want a violet beam.
Anyone know where I could get one?

Request one in the B.S.T section. Most of the ones commercially available are going to be around a Watt. The 445nm diode that is in the lasers is capable of putting more than 1W so the price is likely to be the same for a 200mW as for a 1+Watt... the only difference being that it may require less heatsinking and a less expensive driver.

The general opinion on this forum is that you should DIY it. Alternatively, grab yourself one of the ones from Rayfoss or O-like and then twist the pot on the driver to reduce the power.

What's your budget?

And btw, welcome to the forum!

Stay safe and happy lasering!!

Yeah, I've been searching and found most of them being either 1w or 405nm. I don't mind if the power is higher, it's just that anything under $150 and 200mw + would be great. I'm not so confident on DIYing it.

Real 1W 445nm blue Laser torch/waterproof/focusable [OL-1W-445] - $209.00 : Welcome to O-Like.com, Your source for laser products
That's quite good , but I'd like something under $150, or around that price.

Oh, and thanks for the warm welcome. I've been looking around this forum for quite a few days now, so I'm getting familiar with everything around here.

In my opinion, 1W O-like lasers that AMN has post, is better than anything you have in mind.

it's more expensive, but ONLY 209 bucks, I think that it's a very good price man.

But the con, is that with 1W, you must be very much caution that 200mW.

I think it's a very good buy, but you must buy a googles.

Also, in dragonlasers you have 447nm blue lasers, from 200mw to 1W.

You have this option:
Aurora Series 200mW Blue Laser Pointer, Circular Beam :: Blue Laser Pointer ------- 447nm Laser ----- Aurora Series Lasers :: Handheld Lasers :: Dragon Lasers

A CNI laser. Good quality. But this one is a pen style and has less efficiency.

Also, you can check out in Rayfoss.
For example:

And please, buy a googles.

Think about ; )

Thanks for your reply!

Yeah, that O-like lasers seems like a great buy, and well worth the price, but I was looking for something under $150, or somewhere around that price. Yeah, if I were to buy it I would get safety goggles too, so that'd be good. But again, the main problem is the price.

And the dragonlasers one, is it focusable?

The rayfoss that Antoniio linked seems to be the best not-DIY option for you.
But you can always ask a member to build it for you and see if you can get a good price.

Oh, shit hahah :$

Aurora series isn't focusable, is a simple pen style.

I don't know if the Spartan is Focusable, but it seems that isn't it.

Anyway, it's good for burning! It is 1W, very powerful.

I just saw his edit now that you pointed it out, that looks like a great laser, although I prefer a push switch, not a momentary button. But I found another Rayfoss, and for only $10 more then the other one, it's a push switch at the back, and it's 1W (It says 800mw-1W)
I'll consider that one. I'll save a little more $$$ and get that one most likely, unless I can find another one.

I think I'll go for this Rayfoss one:

Please tell me if you see any flaws with this.

EDIT: I just saw this video on Youtube featuring the Rayfoss laser (link above), and it appears to have a rectangular dot, but on the website, it's advertised as a circle dot.
Now I have no idea whether it's a rectangular dot or a circular dot?

Please tell me if you see any flaws with this, and also, what does it mean by 30 seconds duty cycle?

Man this is a good choice. I know this laser, and the beam is amazing. You can see it at daylight with no problem.
Sorry, but I don't know exactly what flaws it can have.
mmm, I think that it means that is recommended, have ON the laser in 30 second cycles, because probably don't have a cooling system, but this last Is a guess.
Here some videos:

YouTube - Laser 1W quemando

The laser of the video isn't that it we are talking. Is this:

The other laser is this:

Wait, which one do you recommend? The first one or the second one?

Antoniio · Mar 20, 2011

mmm, I don't know exactly how they differ, but both seems very good.

I prefer this one, because it seems more little and compact, and is focusable and watherproof.
www.rayfoss.com

I think the other have a more Duty Cycle, SO, for burning probably is better in this area.

Sorry, but I don't know why is 10 dolars more expensive.

As I say, the both seems very good.

Yeah, me too.
I fear the other one has a rectangular dot.

This one has a circular dot right? - www.rayfoss.com

Yes the dot is circular. You can check this in the video I've posted.

But according to the Rayfoss specifications, the other one, also has a circle dot.
:undecided:
But in the video you've posted... I don't know. Anyway, latter, have higher duty cycle, this is very good, and if the dot is rectangular, you can make it smaller.

I think I'll go for the $179 one, it's $10 less, meaning I'll be able to get it sooner. And also, I've seen videos of the dot being circular, and it performing exactly how I would like my laser to perform. Thanks a lot.
So I'll save a bit more cash and pick that one up, and if the dot turns out to be rectangular, I'll just ask for a refund.

Thanks to everybody for their help!
