Laser Medium Holding Structure for Heat Release and Stress Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing laser medium units face challenges in effectively addressing deterioration due to both stress birefringence and thermal birefringence, and temperature control is difficult due to insufficient heat conduction between the C-ring and the laser medium.
Innovation Solution
A laser medium unit design featuring a holding body with a deformation allowing portion that extends from the inside to the outside, providing a wide contact region along the outer edge of the laser medium for efficient heat dissipation and stress relief, including slits for uniform stress and heat distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a C-ring or like structure is used as a stress relieving portion, then stress birefringence deterioration is curbed, but heat conduction becomes insufficient leading to thermal birefringence deterioration
Solution Approach 1:
The patent merges the stress relieving function and heat conduction function into a single integrated holding body structure. The holding body includes both a stress relieving portion (protrusion) and a heat conduction portion (contact region extending along the outer edge), combining two previously separate functions into one component that simultaneously addresses both stress birefringence and thermal birefringence control
Solution Approach 2:
The holding body is designed as a multi-functional component that performs multiple roles: it holds the laser medium, relieves stress through the protrusion portion, and conducts heat through the contact region. This universal design eliminates the need for separate C-ring structures and achieves both stress and thermal management in a single element
2Temperature
If the contact region extends along the outer edge of the laser medium, then heat conduction efficiency is improved, but stress distribution may become uneven
Solution Approach 1:
The holding body features localized functional regions with different properties: the contact region extending along the outer edge provides enhanced heat conduction where needed, while the protrusion portion provides targeted stress relief at specific locations. This local quality differentiation allows optimal heat dissipation without compromising overall stress distribution uniformity

AI summary
Disclosed is a laser medium unit that includes a laser medium and a holding body. The laser medium has a pair of end surfaces. The holding body surrounds the laser medium when viewed form a direction intersecting with the pair of end surfaces and holds the laser medium. The holding body includes a deformation allowing portion that extends from the inside to the outside of the holding body when viewed from the direction intersecting with the pair of end surfaces. The laser medium and the holding body are in contact with each other. A contact region of the holding body with the laser medium has a width in the direction intersecting with the pair of end surfaces and extends along a side surface of the laser medium when viewed from the direction intersecting with the pair of end surfaces.
