here is my latest creation. I harvested two LOC diodes and built this precision beam combining system. Each LD does around 210mw at 360ma each. I combine them with a PBS (polarized beam splitter cube) and have a final output of 410 to 420 mw. Total package size is 2.5 x 3.5 x 1.25". The system is designed to be very precise adjustment for beam overlap ease. I can overlap the beams at well over 200 feet with no problem. This is a prototype beam combining system that I will be offering to everyone here very shortly. IF you are interested in one of these systems let me know via a PM and I will get it going for you.

And here is a picture of it down my driveway. I have a very long driveway about 200 feet at least.

If you set up the lasers to be adjustable, you should be able to get the beams aligned. That should eliminate the far field divergence.

Peace,
