1.5-Micron Amplifier for High-Average Power, Phase I

Completed Technology Project

Project Introduction

Aqwest proposes to develop a novel, compact and rugged high-peak power erbium (Er) laser amplifier at 1.5 m to for NASA remote sensing trasmitter. The project will take advantage our novel and highly successful edge-pumped disk laser (EPDL) multi-passed amplifier we are developing for the US Army, Navy, and the Department of Energy (DOE) applications. In Phase I, we will use our existing suite of models to determine the feasibility of a 1.5- m EPDL-based laser amplifier and identify preferred operating regimes. We will test our existing Er:glass laser disk in our existing EPDL test bed to further calibrate/anchor our models over the wavelength range of interest, especially at around 1.547 m. Using this information, we will design and fabricate a new laser disk with optimized Er doping and improved waste heat handling capability for the targeted operating regime, and test its performance under relevant conditions, and confirm the models. In Phase II, we will design, fabricate, test, and deliver a prototype 1.5- m EPDL laser amplifier. More »
