Development of a Prototype 2 mm Fiber-Coupled Seed Laser for Integration in Lidar Transmitter

Completed Technology Project

Project Introduction

Optimize the performance of Gallium Antimonide (GaSb)-based 2.05 mm lasers (previously developed under JPL’s Research and Technology Development (R&TD) Program) for emission at the precise wavelength of 2.05 mm with an angular emission for efficient coupling into polarization maintained (PM) optical fiber
Develop a robust fiber coupled hermitically sealed package to house the diode laser while maintaining its high power and narrow linewidth performance
 Integrate these lasers in the frequency locked system (currently developed under under JPL R&TD Program) to demonstrate a frequency stable laser with at least 10 mW output power (with a 40-50mW goal), ~100 KHz linewidth, and 1 MHz long-term stability
