Description
The CSRayzer Fiber-Coupled PPLN Waveguide Device is a high-performance frequency conversion module engineered for efficient second harmonic generation (SHG) applications. Utilizing periodically poled lithium niobate (PPLN) waveguide technology, it significantly enhances nonlinear optical conversion efficiency compared to bulk PPLN crystals. Designed with a robust, compact fiber-coupled package, it ensures long-term stability and ease of integration into optical systems.
This device accepts PM1550 fiber input at 1560 nm and converts it to 780 nm via SHG with high conversion efficiency, delivering output power up to 2 W. It supports both fiber-coupled output and free-space configurations, making it suitable for a range of high-precision photonic applications. Advanced packaging techniques allow the device to handle pump powers up to 5 W while maintaining excellent thermal stability and polarization extinction ratio (≥18 dB).
Integrated with a TEC and 4-pin electrical interface for temperature control and monitoring, the device ensures consistent performance over a wide operating temperature range of -20°C to +70°C. Ideal for quantum optics, precision metrology, and high-resolution spectroscopy, this waveguide module delivers exceptional efficiency and reliability.
