Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional external resonator structure is used with traditional alignment methods, then alignment can be achieved, but alignment time is excessive and alignment precision is insufficient
Solution Approach 1:
A reflection member is introduced as an intermediary component between the first and second laser elements. This reflection member facilitates the alignment process by providing a reference surface for adjusting the relative angles and positions of the laser elements, enabling precise alignment without requiring complex direct alignment procedures between the laser elements themselves
Solution Approach 2:
The alignment process is divided into preliminary steps where the reflection member is first positioned and adjusted, followed by the sequential alignment of laser elements relative to this established reference. This preliminary setup of the reflection member simplifies subsequent alignment operations and reduces overall alignment time
2Power
If conventional external resonator structure is used, then laser oscillation can be produced, but output level is insufficient
Solution Approach 1:
The patent merges the functions of the external resonator components by positioning the first and second laser elements to face each other with a reflection member, creating a compact resonator structure where the laser elements themselves serve as the resonator boundaries, eliminating the need for separate external resonant mirrors and achieving high output in a simplified configuration

Implementation Method 1
Within a laser resonator, it is necessary to amplify laser light by leading laser light to oscillate repeatedly to continuously produce stimulated emission
Implementation Method 2
disposing the reflection member in an optical path of the light emitted from the first laser element; adjusting a relative angle between the first formation face and the reflection face while causing the first laser element to emit the light and producing a laser oscillation between the first laser element and the reflection member
