Dear Users,

please be aware of an inconsistency between the implementation of the
*laserWavepacket* and its documentation in `laserConfig.param`.

In the all previous releases, including *0.1.1*, the input parameter is
by sqrt(2) off compared to what is documented.

For details to either update the implementation or your adjusting your
current input please read:
  https://github.com/ComputationalRadiationPhysics/picongpu/pull/1312

The wavepacket laser is a test/debug laser profile. It is enabled if
`componentsConfig.param` has a line set to:

  namespace laserProfile =3D laserWavepacket;


The current `dev` branch (unstable) fixed the problem by changing the
implementation. The upcoming 0.2.0 release will include the fix as well.


Best regards,
Axel Huebl
