Title: Hannes Winter and Intracavity Frequency Conversion

Introduction

Hannes Winter is an inventor associated with Hamburg, Germany, and Coherent Lasersystems GmbH & Co. KG. His work includes a patent concerning frequency conversion in a solid-state laser resonator.

Latest Patents

Winter is named on 1 patent: “Intracavity Frequency Conversion in Solid-State Laser Resonator with End-Pumping.” The invention describes end-pumping a solid-state gain medium to generate an intracavity laser beam, then using a nonlinear crystal inside the resonator to convert part of that beam’s frequency. It controls the converted beam’s output power and at least one beam parameter by adjusting pump power and resonator loss. Because both the pump beam and intracavity beam contribute to thermal lensing in the gain medium, the method can adjust output power and beam parameters independently.

Career Highlights

The patent reflects Winter’s work in solid-state laser technology, particularly the control of frequency-converted laser output through coordinated adjustments to pumping and resonator loss. He is associated with Coherent Lasersystems GmbH & Co. KG.

Collaborations

Christian Hagemann is identified as Winter’s coworker. The available information does not specify their roles or describe a particular joint project.

Conclusion

Hannes Winter’s patent addresses a method for independently controlling key characteristics of frequency-converted laser output in an end-pumped solid-state resonator.
