Stress in excess of one of the Absolute Maximum
Ratings may damage the laser. Please note that a
damaging optical power level may occur although the
maximum current is not reached. These are stress
ratings only, and functional operation at these or any
other conditions beyond those indicated under
Recommended Operational Conditions is not implied.
