ASSP 2003: Yb:S-FAP Multipass Side-Pumped Amplifier

Bhabana Pati, Yelena Isyanova and Peter F. Moulton Q-Peak, Inc., 135 South Road, Bedford, MA 01730 www.qpeak.com

We report a diode side-pumped, single-stage, multi-pass Yb:S-FAP amplifier designed to achieve high pump brightness, uniform absorption, and high amplification. We demonstrate highly efficient operation of the amplifier with an input signal from a Nd:YLF oscillator.
