ENVELOP {Keyword}  
Shape of the efield pulse used in realtime propagation (RTP) calculations. [Edit on GitHub]  
This keyword cannot be repeated and it expects precisely one keyword.  
Default value: CONSTANT  
List of valid keywords:

INTENSITY {Real}  
Intensity of the electric field. For realtime propagation (RTP) units are in W*cm2 which corresponds to a maximal amplitude in a.u. of sqrt(I/(3.50944*10^16)). For a constant local field in isolated system calclulations, units are in a.u.. [Edit on GitHub]  
This keyword cannot be repeated and it expects precisely one real.  
Default value: 0.00000000E+000 
PHASE {Real}  
Phase offset of the cosine given in multiples of pi. Used in realtime propagation (RTP) calculations. [Edit on GitHub]  
This keyword cannot be repeated and it expects precisely one real.  
Default value: 0.00000000E+000 
POLARISATION {Real} {Real} {Real}  
Polarisation vector of electric field [Edit on GitHub]  
This keyword cannot be repeated and it expects precisely 3 reals.  
Default values: 0.00000000E+000 0.00000000E+000 1.00000000E+000 
WAVELENGTH {Real}  
Wavelength of efield field for realtime propagation (RTP) calculations. [Edit on GitHub]  
This keyword cannot be repeated and it expects precisely one real.  
Default value: 0.00000000E+000  
Default unit: [nm]
