The DC-285/100-PM-Yb-ROD represents the pinnacle of active gain fibers. The rod is polarization-maintaining and has an effective area above 4500 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 fibers. The rod is aimed at high peak-power pulsed amplifiers and has been shown to handle mega-Watt peak-power levels.
The multimode pump light is guided by our proven airclad technology, ensuring low loss, high damage threshold and a large numerical aperture (NA). The large NA relaxes tolerances on coupling optics and facilitates the use of lower brightness diodes.
The DC-285/100-PM-Yb-ROD is a rod fiber with an outer diameter of 1.7 mm – bridging the DPSS and fiber 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. The rods are available with large AR coated end-caps in a range of standard lengths. Other configurations are available upon request.
