LASCAD is custom software for analysing laser cavities. Given the absorption profile in the rod, it can calculate the gain profile, resonator stability, mode structure etc.

The absorption data was entered into LASCAD as follows:

As an example of LASCAD's capabilities, the temperature distribution inside the laser rod based on the absorbed energy computed by ZEMAX was simulated and is shown here:



Note the orientation of the crystal is reversed from the ZEMAX drawings, so the crystal is being illuminated from the right hand side in this graphic.
