Multiple diodes in a host?

Now I know people have done this before. How hard/expensive is it to have 2-3 M140 diodes in a host and combine them in 1 beam? Is this worth doing or more trouble than its worth?


Thanks

If you're going to go with a dual diode laser don't waste your money on M140 diodes.
The parts are expensive and the difference between a 9mm diode and a M140 diode will only a small difference is the grand total of a multi diode laser.

Two beams can be combined with a PBS which in my opinion is easy enough to do, 3 diodes will require knife edging (check the beam combining guide in my signature)

I like to see builds outside of the typical diode, driver, lens, host.
Go for it, it's loads of fun.

Check out ARG and Ricktrent also let me Google that for you

I have been thinking about alignment/diversion of combined beams... If you put a lens on the combined beam will the beam be corrected properly into 1? IK there will be power loss, but it may be worth it for a better combined beam?

Knife edging stacks beams close to each other.

Using a PBS the beams will actually overlap, if aligned right they will never split.
