can two small laser diodes be joined into one laser housing by drilling the back of the housing oval shaped to fit two 200mw red laser diodes into one housing focused through one glass lens to get a combinded higher output than just a single laser diode as one ''beam''? If you have tried this please resond asap.

Short answer = No.

There are ways to combine beams, but not with the process you have described.

The method you describe would not give you a single beam with double the power.

However, if the tolerances of your build were precise enough, you could create two parallel beams, so close together, that they and the beam spots they create, would look, to the naked eye, as one brighter, fatter beam and spot. -and if you put two, 200mw beams on the same spot, that's a total of 400mw of energy on one piece of real estate, regardless of how they got there.
