Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If two independent resonators and lasers are used to achieve high sampling rates, then the sampling rate is improved, but the device complexity and cost increase
Solution Approach 1:
The patent merges two separate laser systems into a single laser system by using one resonator that can support two different polarization states. The amplification medium is shared between both polarization modes, and a single resonator structure generates both pulse sequences simultaneously. This combining approach maintains the high sampling rate capability while reducing the number of independent components, thereby decreasing system complexity and cost.
Solution Approach 2:
The single resonator is designed to be multi-functional by supporting two orthogonal polarization states simultaneously. Each polarization state can be independently tuned to different resonator lengths, allowing the system to generate two different pulse sequences with adjustable time delays. This universal design enables one resonator to perform the function previously requiring two separate resonators.
2Productivity
If two independent resonators are used, then high sampling rates are achieved, but the cost increases
Solution Approach 1:
The patent combines two separate laser systems into one by sharing the amplification medium and using a single resonator structure that supports dual polarization modes. This merging eliminates the need to manufacture and assemble two complete laser systems, reducing material costs, assembly costs, and maintenance requirements while preserving the high sampling rate functionality.
3Measurement precision
If resonator lengths are synchronized and stabilized, then pulse timing precision is improved, but the device complexity increases
Solution Approach 1:
The patent applies different resonator lengths to different polarization states within the same resonator structure. By allowing each polarization mode to have its own optimized resonator length, the system achieves precise timing control for each pulse sequence independently. This local differentiation within a unified structure enables precise timing without requiring complex synchronization mechanisms between separate resonators.

AI summary
A short-pulse laser system for generating electromagnetic pulses includes: a first resonator having a first beam path and a first resonator length; a second resonator having a second beam path and a second resonator length; and an amplification medium. The amplification medium is arranged both in the first beam path of the first resonator and in the second beam path of the second resonator. The system and method for generating optical pulses enables the generation of a first and a second pulse with an adjustable time delay at high sampling rates. The first resonator of the system is designed such that it supports precisely one first polarization state of the electromagnetic pulses and the second resonator is designed such that it supports precisely one second polarization state. The first and second polarization states are orthogonal to one another and designed with lengths that are variable relative to one another.
