For the conversion media the temperature stability and internal temperature distribution are the most critical parameters. We have pioneered a novel precision heater concept that has been seamlessly integrated into our modules. Furthermore, these modules incorporate a P.I.D. control circuit, which can be effectively managed using the integrated temperature sensor.   Example Setup: Wavelength selector setup only made of PHOTONICPARTS products. The used frequency conversion modules can generate 2nd and 3rd harmonic. This little setup extends the application field of your single wavelength laser system.   ![PHOTONICPARTS\_Wavelength\_Selector](https://photonicparts.com/hs-fs/hubfs/NLO-Package/PHOTONICPARTS_Wavelength_Selector.jpg?width=1000&height=736&name=PHOTONICPARTS_Wavelength_Selector.jpg)   ![PHOTONICPARTS\_NLO\_Dimensions](https://photonicparts.com/hs-fs/hubfs/NLO-Package/PHOTONICPARTS_NLO_Dimensions.png?width=1000&height=651&name=PHOTONICPARTS_NLO_Dimensions.png)     --- **![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
