well, i suspect its less of a 'physicsy' problem than one might hope. generally, when things are working well the output SHG more or less matches the input pulse shape with some extra chirp and/or dispersion which can often be disregarded. in our case, we see this 'good' output shape...

hi all- having a strange (perhaps expected?) problem inserting a BBO into the optical path of a TiSaph fs laser. the issue is that i can achieve strong SHG output, but only with *severe* spatial distortion of the pulse shape. has anyone had experience/encountered this issue in an...
