The prism (Thorlabs PS853) has a listed transmittance of ~28% for both 1064 and 1555 and a silver mirror should be ~97% reflective at both wavelengths, so exiting the cavity there should be 2.0 mW of 1064 and 1.8 μW of 1555.
The cavity mirror transmits 32 ppm and 38 ppm of 1064 and 1555 respectively, so that puts the powers at 62.5 W and 47 mW inside the cavity. The beam sizes were both about 1700 μm 30 cm from the cavity.
