Optical scheme changed

We finished the alignment of the beam, kept the reflection beam and transmission beam at almost the same height as the input(76cm) and got the green. According to the new optical scheme, we need to change to a different kind of dichroic mirror(reflect infrared and transmit green), which we don't have in lab now. And also the present transfer stage we are using for SHG housing take too much space. If we do not change it, it will be hard to realize the new optical scheme. In the attachment, I put the picture of the stage.
