Picosecond Laser with Yb-doped Tapered Double Clad Fiber
In this study, we present results of development fiber picosecond laser by using an active ytterbium tapered double clad optical fiber with mode field diameter of 35 µm and low intrinsic birefringence (1.45×10<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-8</sup> rad/m). We have demonstrated 1040nm/50ps optical source with tunable repetition rate (within range of 1-20 MHz) and an average power of 160 W (peak power 160 kW, 8 µJ per pulse) delivering Gaussian beam with excellent quality (M<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ~ 1.11/1.22).
