Paper Abstract

Pulsed fiber based laser transmitters suitable for optical communications in both near Earth and deep space scenarios are being developed in partnership between JPL and industry. As a precursor to a full space qualification process, commercial components were integrated into a polarization maintaining 1550 nm master oscillator laser as part of a master oscillator power amplifier (MOPA) laser transmitter designed to support pulse position modulation and operation in the vacuum environment. This optically pre-amplified seed laser generated sub-ns pulses at up to 100 MHz with high extinction ratio over variable duty cycle. Test results in both ambient and under vacuum conditions will be reported for this system including a preliminary life-test with over 5000 hours under high vacuum at temperatures ranging from 0 to 40 °C.
