Abstract
In this work, we investigate experimentally coupling of diode laser radiation into a single-mode-fiber (SMF) at high optical power. In particular, nearly diffraction-limited, single-frequency continuous wave (CW) radiation around 1064 nm generated by a distributed Bragg reflector (DBR) tapered diode laser is coupled in a bench-top experiment into an SMF with a core diameter of approx. 6 μm. Misalignment tolerances for efficient SMF coupling are determined through two-dimensional coupling efficiency scans, conducted for an attenuated diode laser beam. The coupling efficiency and the laser beam properties behind the SMF are investigated in dependence on the optical power in front of the SMF. A maximum power ex fiber of 3.5 W at a coupling efficiency of 65 % is reached.
