Develop new single mode (SM) fiber(s) with suppressed Stimulated Brillouin
Scattering (SBS) and other nonlinear effects for High Energy Laser (HEL) beam
delivery fiber. DESCRIPTION:
The Navy is interested in the burgeoning technology area that supports a
High-Energy Laser (HEL) system on naval platforms that can serve a vital role
in naval defensive and offensive operations for ensuring Navy Battle Space
Supremacy and water space management. Currently no such SM fiber with a reduced
loss exists commercially that can carry a HEL over 60 feet, due to SBS and
other nonlinear effects. The Navy seeks an innovative solution for integrating
HEL weapon system or subcomponents through a submarine pressure hull. Potential
integration approaches that are being investigated to install such a system on
a platform include placing beam director and HEL sub-systems separated by a
distance greater than 60 feet. In this case the total optical power (SM
multiple fiber bundle) would need to be transmitted long distance capable of at
least 2 to 3 kW output optical power per SM fiber with a goal to be able to
support a future system having a threshold of 50 kW to a 100kW goal of output
optical power at wavelengths 1 �m, 1.5 �m, and at 2 �m. Developing innovative
SM fiber technology to integrate HEL weapon system subcomponents through a
platform will facilitate the inboard/outboard integration of a HEL weapon
system. The innovative fiber/fibers design should have a suppressed SBS and
other nonlinear effects. Total optical loss of the innovative SM fiber/fibers/optical
cables should be less than 0.5 dB of the length of 60+ feet. PHASE
I: Design, model, and develop a concept for a SM fiber to transmit high optical
power between HEL subsystems. Demonstrate feasibility of the concept by
modeling and simulation and/or limited demonstrations in a laboratory
environment. Determine that the selected technology is feasible and meets Navy
high energy delivery SM fiber optical power requirements in the Description.
Develop a Phase II plan. The Phase I Option, if exercised, would include the
initial layout and capabilities description to build the unit in Phase II. PHASE
II: Fabricate SM delivery fiber with reduced SBS and other nonlinear effects
with total loss of less than 0.5 dB. The High Energy Laser prototype fiber will
be used for evaluation in a representative platform environment. The prototype
should include a complete concept that incorporates HEL power transmission for
a long distance (> 60 feet). Demonstrate an innovative fiber prototype from
modeling, design, and verification test in a laboratory environment in order to
verify that the key system performance specifications of the platform have been
met. Deliver SM fiber for Navy test and evaluation. Prepare a Phase III
development plan to transition to Navy use. PHASE
III DUAL USE APPLICATIONS: Support the Navy in transitioning the technology for
Navy use. Further refine a full-scale prototype that can be integrated and
tested on Navy Submarine test platform. REFERENCES: 1.
