SBIR/STTR
Single-Frequency Semiconductor Lasers Operating at 1.5 and 2.0 microns, Phase II
Project Introduction
While conventional injection seeding sources (such as DFB diode lasers and rare-earth doped solid-state microchip lasers) are available at 1.5 microns, these sources typically lack the ultra-narrow (<50 kHz), ultra-stable output spectrum required for use in applications such as Doppler shift measurements of the tropospheric winds. Furthermore, similar sources which operate at 2.0 microns (a preferred wavelength for space-based atmospheric measurements) are simply unavailable.

Anticipated Benefits
Potential NASA commercial applications include: 1. Ultra-narrow linewidth LIDAR injection-seeding sources for Doppler shift measurements of the tropospheric winds. 2. Narrow-linewidth eyesafe pump sources for 3D LIDAR imaging for autonomous precision landing including hazard detection and avoidance Potential Non-NASA commercial applications include narrow-linewidth eyesafe pump sources for: 1. Military ? Infrared countermeasures, eyesafe rangefinders, eysafe 3D LIDAR imaging for surveillance, and unmanned autonomous ground and airborne vehicles 2. Medical ? Tissue bonding, dentistry
