Yuhang and Michael
We rearranged the OPO optical layout to use proper photodetectors as mentioned by Yuhang. The layout with breadboard spacing (not to scale) is shown in figure 1. A photo of the setup past L1 is shown in figure 2.
The following components are used. Some of them I'm not sure though:
Laser: Lightwave laser
WP1: ?
WP2: ?
KPX1: KPX094AR.33
BS1: ?
KPX2: KPX094AR.33
KPC: KPC034AR.33
L1: ?
