RP Resonator laser cavity design

It can be used to design and optimize optical resonators. Not only can the resonator characteristics be simulated, but the software can calculate the effects of thermal lens effects, offsets, dispersions, Gouy phase shifts, degeneracy, etc. on beam radius and cavity patterns. The software can also be used to design a laser cavity for a given requirement, such as a given mode size at a particular location, minimum sensitivity, thermal lens effects and offsets, beam quality with minimal distortion, etc. Welcome to contact us!

ABCDEF matrix algorithm:

The calculation of the RP Resonator is based on an extended ABCDEF matrix algorithm. Compared to the ABCD matrix algorithm commonly used, it can not only calculate the mode radius, but also calculate the change in beam position due to endoscopic offset.

In addition, it can also handle wavelength-dependent refraction, such as refraction in a prism, and in the resonant cavity of a mode-locked laser, its dispersion compensation is done by a prism pair. The software calculates the optical path of different wavelengths and the resulting dispersion.

Linear and ring cavities can also be treated as one-way propagation as beams output from the laser resonant chamber. For the ring cavity, the path of the beam can be automatically closed, that is, the orientation of the first and last mirrors and the length of the path between them can be automatically calculated. The resulting settings can be displayed graphically to immediately identify possible erroneous inputs.

Specific functions and applications:

• Analyze existing resonator designs, such as checking their stabilization areas, collimation characteristics, dispersion effects, etc.
• Makes it easy to optimize complex cavity designs, such as optimizing laser performance. Refine researchers’ understanding of resonant cavities. For example, various parameters are
• demonstrated through numerical simulation.
• The software comes with a very powerful scripting language and is accompanied by a script wizard function, which makes it easy to generate large sections of script code by filling out forms (simple input numbers or mathematical formulas).
• The power of a scripting language means greater flexibility. For example, the user can define a model of an optical cavity containing multiple laser crystals, etc.
• In contrast to other similar software, RP Resonator allows users to parameterize the cavity characteristics. This means that users can define them using mathematical expressions, rather than just defining simple parameters such as cavity length, radius of curvature of the mirror, etc. In the resulting image, the user can also observe the characteristics of the optical cavity at different locations. Combined with scripting languages, there is great flexibility in the user development process. This feature is hard to find in other similar software.
