Hello, I am new here! I would like to ask which is the better way to focus one red 650nm and one blue 250nm beam together in one beam. What I know is that red is focusing after blue so I used a focal lens (1.5m) for the red beam. Thank you in advance!

Sounds like this ^^ is what you want.

Would also like to see pictures of these dye lasers, cause YAG pumped dye is awesome.

Dichros are what you need, pbs are also fine if you don't have problems with orthogonal polarization.
