Superposition of two laser beams

[QUOTE="cks, post: 1939385, member: 37272"] I want to superpose two laser beams to create the beat frequency. I design the system to be like this . Two laser beams come from A and B meet at the center of the PBS, so that two laser beams going out to C and D. I tune the laser beams A and B such that the laser output at C and D superimpose. In mathematical terms. E1=Aexp[i(k1x-w1t)] E2=Bexp{i(k2x-w2t)] So, the superimposed state is E=E1+E2. My problem is, I use a polarizing beam splitter. so the output laser beam have Electric field that are orthogonal to each other. It'd be nice if I can get parallel E field so that the superposition would be much better. How can I do that. How can I make the two orthogonal electric field to be parallel to each other? [/QUOTE]
