If any further assistance concerning your individual setup is needed, feel free to contact us. Depending on the setup and applied power, thermal bonding of solid-state laser crystals plays a key role in achieving stable and high-performance amplification power. Due to our design concept and solder joining technology, a radial heat dissipation is achieved with exceptional homogeneity. After years of dedicated research and development for high-end laser beam sources supported by thermal simulations, we have innovated a distinctive approach for mounting and cooling solid-state laser crystals.   ### Cooling water flow of an actively cooled rod crystal package: ![PHOTONICPARTS_Crystal_Cooling](https://photonicparts.com/hs-fs/hubfs/Crystalpackage/PHOTONICPARTS_Crystal_Cooling.jpg?width=500&height=349&name=PHOTONICPARTS_Crystal_Cooling.jpg)   ### Exemplary temperature distribution of an end-pumped rod crystal: ![PHOTONICPARTS_Lasercrystal_Thermosimulation](https://photonicparts.com/hs-fs/hubfs/Crystalpackage/PHOTONICPARTS_Lasercrystal_Thermosimulation.png?width=500&height=237&name=PHOTONICPARTS_Lasercrystal_Thermosimulation.png)   Amplifier setup examples:   ### Example 1: Single-Pass Configuration ![PHOTONICPARTS_Amplifier-Setup-3](https://photonicparts.com/hs-fs/hubfs/Crystalpackage/PHOTONICPARTS_Amplifier-Setup-3.png?width=750&height=416&name=PHOTONICPARTS_Amplifier-Setup-3.png)   ### Example 2: Double-Pass configuration ![PHOTONICPARTS_Amplifier-Setup-4](https://photonicparts.com/hs-fs/hubfs/Crystalpackage/PHOTONICPARTS_Amplifier-Setup-4.png?width=750&height=285&name=PHOTONICPARTS_Amplifier-Setup-4.png)   ### Example 3: Contra-directional double pass configuration ![PHOTONICPARTS_Amplifier-Setup-1](https://photonicparts.com/hs-fs/hubfs/Crystalpackage/PHOTONICPARTS_Amplifier-Setup-1.png?width=750&height=262&name=PHOTONICPARTS_Amplifier-Setup-1.png)   ### Example 4: Single pass configuration (alternative) ![PHOTONICPARTS_Amplifier-Setup-2](https://photonicparts.com/hs-fs/hubfs/Crystalpackage/PHOTONICPARTS_Amplifier-Setup-2.png?width=750&height=388&name=PHOTONICPARTS_Amplifier-Setup-2.png)   Example for crystal rod dimension: e.g. diameter d=1mm; length l=5mm   ![PHOTONICPARTS_Crystal_Dimensions](https://photonicparts.com/hs-fs/hubfs/Crystalpackage/PHOTONICPARTS_Crystal_Dimensions.png?width=800&height=739&name=PHOTONICPARTS_Crystal_Dimensions.png) Heatsink dimension can be easily adapted to other geometries.   --- **![PHOTONICPARTS_Logo_Full](https://photonicparts.com/hs-fs/hubfs/Logos/PHOTONICPARTS_Logo_Full.png?width=250&height=27&name=PHOTONICPARTS_Logo_Full.png)** Ericsson-Allee 1 52134 Herzogenrath Germany [Follow us on LinkedIn](https://www.linkedin.com/company/photonicparts/) [envelope icon](mailto:info@photonicparts.de) [Follow us on Facebook](https://twitter.com/PHOTONICPARTS)       - [Technology](https://photonicparts.com/technology) - [Products](https://photonicparts.com/products) - [Solutions](https://photonicparts.com/solutions) - [Company](https://photonicparts.com/about_us) [![PHOTONICPARTS_Logo_Icon](https://photonicparts.com/hs-fs/hubfs/Logos/PHOTONICPARTS_Logo_Icon.png?width=1200&height=867&name=PHOTONICPARTS_Logo_Icon.png "PHOTONICPARTS_Logo_Icon")](https://photonicparts.com) [Legal Notice](https://photonicparts.com/legal-notice)| [Privacy Policy](https://photonicparts.com/privacy-policy) © 2026 PHOTONICPARTS
