CD player laser test jig

[Fantastic]

Does anyone have a circuit to test the laser's optical output in a CD player. Something like an opaque opto diode with an amplifying stage. While it need not have any absolute measurement value it could be used to compare the output of a good unit with a bad unit.
Thanks.
