Summary
A comprehensive treatment of a high magnification output coupler has been presented. It is important to resample the POP beam at the primary mirror to account for losses due to the magnification of the cavity.
The model can be easily extended:
- Further beam propagation may be analyzed by setting appropriate surface and distance of propagation
- Propagation of both wavelengths in the CVL can be studied
- The influence of output meniscus lens can be studied
- The influence of the reflection coefficients
The Physical Optics model allows detaild modelling of the cavity.

That was a good article to follow
Is it possible to analyse laser beam quantum mechanically

Thanks. I want to know more as this. I hope that one day we can design and analyse DPSSL with ZEMAX.

The article is clear, but I have a question: why do you evaluate just 2 full-trips?
How do you assess that the cavity intensity distribution reaches the steady-state (i.e. we have the correct resonant mode of the cavity) after 2 round trips only?

Comment by unknown user: The article is clear, but I have a question: why do you evaluate just 2 full-trips? How do you assess that the cavity intensity distribution reaches the steady-state (i.e. we have the correct resonant mode of the cavity) after 2 round trips only?
Answer: The mentioned assumption may be prooved by comparing of output radiation after 2 and 3 full passes - it will be no difference.
