Deniz can calculate the maximum theoretical conversion efficiency of 780 if we know the amount of 1064 and 1555 in the cavity. After a silvered mirror and a prism, I measured 0.55 mW maximum of 1064 when locking, and 0.50 μW of 1555.
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.
