I mean I put the gaussian source at (center 0 0) and have a propergating beam along x. But I don't want the waist at (center 0 0), I hope to change the waist to (center 15 0), for example.
Just like you place some lens before the laser and change the postion of its waist, whereas the position of source don't change. How to do it in MEEP? Thank you. mario __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
