Experimental setup of the folded y-cavity. M1 acts as an output coupler for the 1064 nm arm with a reflectivity of 99.4%. M2 is HR at 1342 nm and HT for the pump at 808 nm. M3 is a dichroic mirror allowing the separation of the two arms with HT 1064 nm and HR for 1342. M4, M5, and M6 are HR 1064 and 1342 nm with the respective radius of curvature: 150, 100, and 150 mm. The dark blue arrows show the pumping.
