Mixed Beam Experiment

[diachi]

Hello, i plan on focusing two lasers into the one beam, but first i need to know where i can get laser modules that are around 50mW i need one green and one blue or one red and one green, either will do.

i also need to know if my 32V 3000mA power supply would power both these laser without a problem when wired in parallel

Bellow is my plan, thats how im gonna focus the beams ...

 

[diachi]

thanks

 

[diachi]

well ill need something visible with a combined power of around 50mW (got a low budget.)

 

[diachi]

well i think ive got the right tools, i was originally planing for green and blue, but the blue costs too much for power levels , thanks agian

I plan on using a 35mW module from DX and then a whatever red one i can get....

Bellow is how i plan in connecting the diodes

 

[diachi]

yeah i know what your saying, i did it like that cause of budget limits and the fact i already have a power supply

 

[diachi]

i was gonna use the DX laser that has both red and green diode driver boards and just modify it slightly to get both of them running at once ?

 

[diachi]

lol yeah and then just buy a mount for it?

 

[diachi]

If i got the DX laser with the red and the green output channels (on one PSU) i could connect the output channels in parallel and then just turn it on, it should probably power both diodes at around 25mW each and give me a combined power of around 50mW (if that actually works)


and yeah those mounts should work

 

[diachi]

i dont know .... mainly cause i dont have much money to spend on this.

 

[diachi]

just found a 100mW red laser on DX for 29$ that cant be right

The 70mw lab style red from DX is cheap you can connect one of the 5mw green modules to the green output and turn them on and off, indipendantly, using the TTL flying lead.
As the red is adjustable you can match the output intensity to get a good yellow.
It is not as many mw as you say you want but a 5mw green is quite bright, depends what you intend to do with it.....

* Edit...The only problem I have found with the circuit is that the adjusting pot is of low quality and I have killed a couple of red LD's with it..... It may be that I was just unlucky :-[

 

[diachi]

ok , thanks

one last thing:

Would my power supply work, its just like a normal powerpack with a + and - output, it goes up to 32 volts and i think 3A

 

[rog8811]

The DX module needs a 5v input, it is not designed to handle much more so be careful with it

[diachi]

thats alright the voltage and ampage is variable so it should be fine and theres a digital volt meter that reads your output voltage (im suppose ud have guessed that)

 

[rog8811]

(im suppose ud have guessed that)

I did guess that

It is just so tempting to turn the wick up a bit....then a bit more....read around the forum as ABCT suggests, there is a lot of info in the review section on the DX lab laser.
