Abstract
In this contribution, we report a home-made pump-gain integrated fiber (PGIF) based on side-pumped fiber laser scheme. PGIF with a 60cm coiling diameter is characterized in a bidirectional amplifier configuration, 1.6kW laser output with excellent beam quality (M2=1.3) is obtained. The result indicates that PGIF has great potential in power scaling of high power fiber lasers.
