ok, let me re-run the numbers

begin---> 200mw. then we have around 3% loss at each optima lens, so that leaves us with 194mw. then we hit a good quality frost surface ar coated mirror. Let's assume another 2% losses, so we are left with 190mw.

then, we have to decide, clipping or no clipping when knife-edging? if no clipping, no losses. then, we have the telescope and pbs and i don't know what else is in that box and all this should have a combined loss of less than 8% to hit the 1.4 mark

well, seems duable, but with slightly "overdiven" diodes
