Paper Abstract

In this paper we present for the first time to our knowledge an efficient and rugged light source in the visible, based on a gain switched Yb3+ doped fiber laser source, frequency doubled by a non-critically phase matched LiB3O5 crystal. The simple setup proves to be robust and durable against back reflections, which in turn remove the requirement for optical isolators along most of the system. Gain switched fiber lasers typically produce long pulses with low peak power, which are not optimal for frequency conversion applications. However, as opposed to MOPA laser configurations, based on a semiconductor laser diode as a seed source, the narrow spectral line width and chirp free operation of gain switched lasers render them suitable for efficient frequency doubling.
