Twin Blue Beams !

[Accutronitis]

I like prefer the term, lasers can burn a hole in your pocket. Because it true both ways.
I actually have two NUBM44's for that purpose Alaskan, but have never got round to it. Now that's a scary thought.

Oh that is using two 44's ? That's not at all like I was thinking......

Lol. PBS stands for polarising beam splitter but they can also combine beams of different polarisation. Can you imagine 12-13w of 450 depending on losses?

 

[Accutronitis]

That would be a true wicked laser And a mother to keep cool !

 

[Alaskan]

What is nice about PBS is they combine the beams coaxially, one right on top of the other. However, a wave plate is needed to match up the rectangle shaped diode outputs so the polarity of both diodes have the same footprint through the cube, otherwise without the WP, it would end up being a crossed shape. Then you could follow it up with beam correction

 

[CurtisOliver]

Exactly Alaskan. :beer:
I still need to get some waveplates.

 

[Alaskan]

Just need one

This is for 455 nm, I wonder if it would work at 450?

[CurtisOliver]

It should be ok for 450. I need one for 450 and 465.

 

[Accutronitis]

It's simply amazing what we can do with light these days !

Those are the same two wavelength lasers I have !

At first I was only driving the M462 diode at 1.1 amps at which the M462 diode only outputs 1.382 watts but I bought a Super X-Drive set at 1.8 amps and one of DTR's G-2 lens from him and now it's output is up to 2.203 watts, Big difference ! :thanks: DTR !

I have two NUBM07E's. Amazing! Although I have one meter at 3.7w and the other just over 2.3w. I'm a bit concerned about the 2.3w as it should be performing higher.

What driver are they both using ?

Hey thanks for this link in your sig ! http://darekk.com/kalkulator/wavelength-to-rgb

 

[CurtisOliver]

I'm unsure about the current but both are the same. DTR sells them with x-drives. With diodes like that, you do sometimes see inefficient ones. I could just have a lower power diode.

 

[Alaskan]

What, the meter?

 

[CurtisOliver]

I have a scientech 365. I will have to give them a rerun with a stable surface.

Edit: You're welcome Accutronitis. I find that wavelength to rgb converter very useful. Glad it can be of use to you.

 

[Alaskan]

I also have that LPM, like it.

 

[CurtisOliver]

It is a great lpm. Shame it's got a few burn marks on its sensor now.

CurtisOliver on the NUBM07E 2.3W do you still have the can attached ! i just got one, and am planing to get one with the can
