Abstract:

     This project will demonstrate the feasibility of a
nanosecond, diode-pumped, cavity-dumped laser for application in
space-based altimetry. Under this project, a diode-pumped laser
testbed will be set up in order to test resonator cavity
configuration and electro-optics switch materials. The performance
of two different electro-optic materials, KD*P and KTP, will be
evaluated in the testbed. Alternate solid-state laser materials
for use in generating 0.7 to 0.95 æm output will be critically
evaluated for use in the cavity-dumped laser, based on their
optical, mechanical, and thermal properties. Phase I will
establish the feasibility of developing a space-qualified, diode-
pumped laser for NASA applications in space-based, high-resolution
topographic mapping and atmospheric remote sensing.

Potential Commercial Application:

Potential Commercial Applications:  The nanosecond, diode-pumped
laser will have commercial application as a pump laser for tunable
dye and titanium-sapphire lasers. Commercial applications in
aircraft-based topography and bathymetry, as well as precision
ranging, are possible.
