Hi
I want to model a Gaussian beam source in SQ mode.
The laser specs are,
- wavelength: 532 nm
- 2theta: 0.7 mrad (FW)(1/e^2)
- 2w0: 1 mm (FW)(1/e^2)
- w0 position: laser head output position
- M2 < 1.1
In this situation, the beam waist cannot be a point source.
Then, what should I set(aperture type, object position, etc.. ) for the modeling in the SQ mode?
Thanks in advance
Hello Jeeyoung Lee,
I would recommend using the Paraxial Gaussian beam calculation to get an idea of the Rayleigh length:
So if you are within the Rayleigh length in your system, a collimated beam can be a good approximation.
Then it depends what you need to study in your system. For further information, check our learning path: https://my.zemax.com/learning-paths/modeling-laser-beam-propagation-in-opticstudio/
Do not hesitate if you have any further questions.
