Notes:
1. Operating power is set by the peak operating
2. Operation at temperatures outside the specified
3. Slope efficiency is defined as Po/ IF at a total power
4. Rise and fall times are sensitive to drive electronics
5. Beam divergence is defined as the total included angle

These labels can be found on the individual envelope in
which the VCSEL unit is packaged, or attached to the
shipping package.
