产品详情

仪器简介：

The DC-200/70-PM-Yb-ROD represents the pinnacle of active double-clad fibers. The rod/fiber is polariza-tion-maintaining and has an effective area above 2000 μm2. The very large effective area combined with extremely high pump-absorption of up to 30dB/m pushes the nonlinear thresholds to a new regime in fiber optics. The rod is aimed at high peak-power pulsed amplifiers and has been shown to handle mega-Watt peak-power levels. The DC-200/70-PM-Yb-ROD is a rod-type fiber with an outer diameter of 1.7 mm – bridging the DPSS and fi-ber laser world. The large outer diameter ensures that the extremely large core will not suffer from bending loss. Moreover, the rod is coating free to facilitate thermal management in high-power setups.
