ST2-L delivers 180 W of power within 0.15 numerical aperture of 135 μm core fiber. The pump operates at 969 nm or 976 nm in a narrow wavelength range using internal locking techniques ideal for pumping Yb:YAG material and fiber laser. It uses a new generation of high-power proprietary chip optimized for reliability at high power.
The multimode pump module offers high power, small size, and simplified thermal management. The diode operates as distributed heat sources, allowing air- or water-cooled architectures with predictable high reliability.
The ST2-L Series is a unique solution for the fiber-coupled pump laser market that requires wavelength accuracy. It offers powerful technical attributes in a cost-effective package.
