Laser Diode Simulation - Source Diode

Dear all,

I need a help from the community. 

I would like to simulate a laser diode in Non-sequential mode. I am attaching here the datasheet of the laser diode I would like to simulate. 

On Zemax: I set as Object type → Source Diode

 After having set the wavelength,  the Layout Rays, and the power I am getting stuck on this information:  

  • X/Y-Divergence
  • X/Y SuperGauss
  • Number X’/Y’
  • Delta X/Y

Can someone help me having a look to the file attached (datasheet diode laser) to fill the abovementioned parameters? 

 

Many thanks in advance 

 

Gianluca

Hi Gianluca

I had a quick look at the datasheet.

For the angular distribution, it gives the half angles:

So check the help files. It shows how to convert half angles into αx. I would use the typical value to start of with.

The datasheet doesn’t really give any distribution so you could go for gaussian.

For the spatial distribution, I am not too sure about the size of the emitted area based on the datasheet. There is a mention of an emission point. Maybe you could use a point for the definition.

Otherwise a more simple model to start is the Source Two Angle.
