Does anyone have experience in manipulating the laserDTRM properties under constant/radiationproperties?

Here is a portion of that code:

absorptionEmissionModel localDensityAbsorptionEmission;

// LPBF Parameters
scanSpeed 0.9; // m/s
laserPower 250; // W
beamQuality 0.95;
solidAbsorptivity 1.64e5; // [1/m], 10.1063/1.3243762
liquidAbsorptivity 1e3;
matEmissivity 0.4;

mode "Gaussian";
nTheta 50;
nr 20;
maxTrackLength 0.0002;
focalLaserPosition table
(0.0 (.00015 .00015 0.0002))
(0.0004 (.00055 .00015 0.0002))
(0.0006 (.00055 .00025 0.0002))
(0.0010 (.00015 .00025 0.0002))
laserDirection constant (0 0 -1);
focalLaserRadius 0.00002; // 10.1038/s41467-019-10009-2
laserPower $laserPower;
sigma 0.000012;
qualityBeamLaser $beamQuality;

My question is whether or not I can give the table property to the laserDirection and laserPower in the same format. Would it be exactly the same?

Yes, this should be possible, because laserRadius and laserPower are also of type "Function1" ( Of course you have to consider that laserPower is a scalar.
