Create a 2D Laser Heat Source

i want to implement soldering by laser in a 2D environment. Therefore i use the heat transfer branch. Actually, i created a metal sheet in form of a rectangle with solder in form of a circular segment on it. Now i want to heat up the solder by a laser heat source. I tried to transform the following tutorial "Laser Heating of a Silicon Wafer" into 2D, but i failed.
www.comsol.com/model/download/262531/models.mph.laser_heating_wafer.pdf
I also tried to implement the laser heat source as a boundary heat source. But in that case, you can't implement the profile of the laser beam. What i didn't get anyway, is the "general source" input. What kind of variable is this and how can i transfrom the power of the laser into this variable?
The laser i want to simulate has the following values:
P = 4000 W
Radius of the spot size = 1,4 mm
Form of the laser beam = gaussian pulse
Can somebody explain me how it works?
Thanks a lot.
Greets, Max
