22 February 2012Preliminary results of testing a space-grade laser transmitter for optical communications
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.
