Why is output equal to non inverting input opamplifier
OP's circuit: -



An OPA552 cannot have its inputs relative to either rail closer than 2.5 volts. With 117 mA flowing through the 3 ohm resistor you have the inverting input at 0.351 volts and well-inside the "do not use" area.

Additional information: - 

The output voltage when driving 200 mA cannot be expected to get any closer to either rail than 3.5 volts over the operating temperature range. This may be a problem depending on the laser diode's forward voltage characteristic.
