In response to the U.S. Air Force""s need for fiber cooling and pointing in high power fiber amplifiers of 1kW and up, i2C Solutions propose the development of a conformal thermal ground plane (TGP) technology to interface with heat sinks integrated into the active precision pointing fiber support structure. The result is a highly efficient thermal management solution, with respect to both volume and thermal performance, that is seamlessly integrated with precision pointing capability. Ultimately, the successful implementation of the developed technology will enable the use of revolutionary next-generation airborne laser weapons systems and allow the US Air Force to maintain future air superiority.

Benefit:
If successful, the proposed thermal ground plane technology will allow for higher performing and more reliable high power fiber amplifiers. Beyond the proposed fiber amplifier, the proposed conformal TGP technology could be applied as an improved thermal management system to a broad array of high power electronic systems. Military applications could include unmanned aircraft systems, manned aircraft and directed energy weapon systems among numerous others. Commercial applications could include consumer electronics (e.g., cell phones and laptop computers).

A key challenge toward future directed energy systems is the development of power and thermal management technologies needed to support the laser systems, particularly fiber lasers. I2C Solutions and the University of Colorado have developed a conformal Thermal Ground Plane (TGP) technology that interfaces hard to cool double clad fibers with laser thermal management systems. During Phase II, TGPs will be developed and qualified specifically for a to-be-selected fiber laser system and the Phase II program will culminate with a demonstration of the functioning laser system with the integrated fiber laser TGP by industry partner.

Benefit:
It is anticipated that the developments undertaken will enable an innovative, extremely efficient thermal transport device that can be integrated with a wide variety of products. Military applications range from ruggedize and shock hardened electronics, lightweight power distribution systems, and directed energy systems. Commercial applications that would benefit from this thermal management technology range from consumer electronics to LED illumination. Ultimately the improved thermal performance in a variety of systems leads to better reliability and longer lifetime at greatly reduced cost, weight, and size.
