Abstract
In order to implement the monolithic high power narrow linewidth pulsed all fiber-based laser transmitter by using a MOPA configuration for NASA's active remote sensing spectroscopy, NP Photonics propose to develop the high SBS-threshold, single-mode (SM), polarization maintaining (PM), high power amplifiers for the sub-microsecond pulses with transform-limited linewidth, leveraging on NP's proprietary patented large core SM PM highly Er/Yb co-doped phosphate glass fibers (LC-EYPhF). We will use our proprietary patented single-frequency Q-switched fiber laser seed that we have developed recently in order to make the whole high power narrow linewidth pulsed fiber laser transmitter compact and expandable to spaceborne or UAV platforms. In Phase I, one new SM PM LC-EYPhF fiber with large core of 25 micron will be fabricated and two power amplifier stages using NP's large core highly co-doped Er/Yb phosphate glass fibers will be implemented in order to demonstrate 5-kW peak power and 2.5-mJ pulse energy with SBS-free for NASA's active remote sensing fiber laser pulses at 765 nm by using NP's SINGLE-MODE phosphate fiber amplifiers.
