This paper presents an Yb:KGW laser-based intracavity image upconverter designed to enhance mid-IR imaging. Traditional mid-IR imaging faces limitations in sensor efficiency, resolution, and cost. Our approach uses IR to visible frequency shift imaging with non-linear Sum-Frequency Mixing (SFM) processes for real-time imaging using Si-based CMOS detectors. Key improvements include the use of a CPLN crystal for increased spectral and angular acceptance, broad SFM pump beams for high spatial resolution, and Q-switched intracavity conversion to boost intensity and compensate for efficiency reduction tradeoffs. Additionally, we demonstrate that asymmetric laser modes within the cavity enhance image resolution. Results show successful real-time upconversion of mid-IR images to NIR. These characteristics pave the way for future high-performance mid-IR image upconverters and applications.
