Abstract

The Navy requires high power laser sources that can provide multi-Watt output power levels in the mid-infrared for optical countermeasures of anti-ship missiles. Current state of art laser transmitters, consisting of diode-pumped solid-state lasers and optical parametric oscillators, have demonstrated the required optical power and wavelength in the mid-infrared spectral region. However, these laser systems are unreliable, requiring constant maintenance due to component failure or optical misalignment. To improve the performance of next generation countermeasures systems, Aculight Corporation proposes a novel laser source based on emerging fiber-optic technology coupled with an innovative wavelength shifter to provide high power, broad bandwidth radiation in the mid-infrared. In the Phase I, experiments will be performed to demonstrate the feasibility of the proposed novel wavelength shifter. A preliminary design of the mid-infrared laser to be built in the Phase II will also be developed. Results from the Phase I will be used in the option task to perform a detailed design of the laser module that will be built in the Phase II. The market targeted for the proposed compact, high-power mid-infrared laser source is the military production of such lasers for Army, Air Force and Navy infrared countermeasures systems.
