Abstract

We demonstrate a 158 fs 5.3 nJ mode-locked laser system based on a fiber oscillator, fiber amplifier and fiber compressor. Dispersion compensation in the fiber oscillator was obtained with a solid-core photonic bandgap (SC-PBG) fiber spliced to standard fibers, and external compression is obtained with a hollow-core photonic bandgap (HC-PBG) fiber.

The insertion loss is relative high compared to other components, but can be compensated by the high single pass gain of ytterbium. Insert: image of the SC-PBG fiber (top) and HC-PBG fiber (bottom).
