The YD1025 Fiber Block 1.8 Module is an optimal solution for power amplification of high-power, high-energy ultra-fast fiber lasers. The gain unit of the amplification module is the PM40/200DC YDF fiber independently designed and manufactured by YSL Photonics. The fiber combines a high-concentration ytterbium-doped core with a micro-structured fiber design. While maintaining flexible bending characteristics, it can achieve single-mode polarized laser amplification. The modular packaging process facilitates industrial production and the construction of research platforms.

Features:

• Signal Input Fiber: PM15/250 SC, single-clad fiber with a core diameter of 15 μm, which can be fusion-spliced directly with the signal fiber for signal injection.

• Gain Fiber: Integrated PM40/200DC YDF fiber, operating in single-mode polarization-maintaining.

• Signa lOutput End: An AR-coated end cap has been fusion-spliced to prevent end-face damage and reflection.

• The module integrates an efficient water-cooling system with quick connectors, ensuring excellent heat dissipation performance and meeting the requirements of long-term maintenance-free operation.
