Laser Resonator Cavity Modeling in Zemax
In this video, I am presenting a laser resonator cavity modeled in Zemax's non-sequential mode. This model includes six key components:
-
Pumping Source:
- Located on both sides of the cavity.
- Represented by the orange components.
- Responsible for light emission into the cavity.
-
Mirrors:
- Two mirrors are included in the model.
- Material: Mirror.
- Function: Reflects light back and forth to amplify it.
-
Volume Detector:
- Located in the middle of the cavity.
- 3D shape form.
- Detects light intensity at different locations within the beam.
-
Cylinder Volume (Gain Medium):
- Material: Glass (PK7).
- Amplifies the light as it travels between the mirrors.
When light is emitted from the pumping source, it travels back and forth between the mirrors, being amplified by the gain medium. The detector measures the light intensity, which varies across the beam.
Light Intensity Distribution
The light intensity distribution in the cavity is bell-shaped, with the maximum intensity at the center, decreasing towards the edges. This is evident when observing the irradiance from the center to the margins of the detector.
Conclusion
This cavity modeling in Zemax's non-sequential mode provides valuable insights for those interested in building a laser cavity. The model demonstrates how light behaves within the cavity and can serve as a guide for similar projects.

Here I'm presenting a laser resonator cavity in Zemax non-sequential mode. This model includes six objects: 1. The first two are the pumping source, located at both sides of the cavity.
This pumping source offers light emission into the cavity. 2. The next two are two mirrors, which reflect the light back into the cavity and amplify its magnitude. 3. In the middle, there's a volume detector, which is 3D in shape. 4. Lastly, there's a cylinder volume, serving as a medium with glass (PK7) material.
When the light is emitted from the pumping source, it goes back and forth between these two mirrors and is amplified by the gain. Our detector is detecting the light intensity at a different location in the middle of the beam.
The difference in 360-degree audacity, as shown in the video, is due to the light's velocity going back and forth in the Z direction. This results in a bell-shaped light intensity distribution from the middle to the sides.
This cavity modeling in Zemax non-sequential mode can offer inspiration for building a laser cavity.
