Abstract
The 10kW-class Chemical Oxygen-Iodine Laser (COIL) device of DLR1 was used for demonstration of efficient power coupling into a commercial fiber optic system (HIGHYAG, Berlin) modified for 1.315 µm radiation. Transmission investigations were performed with different intra-cavity apertures of the stable COIL resonator to match the outcoupled laser beam to the fiber optic system. The transmitted power through the 20 m long fiber with core diameter of 1000 µm exceeded 6 kW during a typical 8 s test run of the laser. The highest transmitted power amounts to 11 kW, the highest value reported in literature. The transmission ratio was above 90%.
