Abstract

The Advanced Integrated Warfare System (AIEWS) will require a high-energy, long-pulse laser that emits wavelengths in the visible to near infrared for optical countermeasures of anti-ship missiles. To meet this future Navy need, Aculight Corporation proposes an affordable and modular diode-pumped solid-state (DPSS) laser that is frequency converted to the visible and near infrared. This modular approach provides the required pulse energy and temporal pulse width by beam combination of multiple, moderate-pulse-energy laser modules. This concept allows for nearly complete coverage in the 425-800 nm wavelength range. The output spectrum can be tailored over this entire wavelength range, making counter-countermeasures on the threat impractical. In the Phase I, analysis and breadboard experiments will be performed to demonstrate the feasibility of the modular laser concept. Results from the Phase I will be used in the option task to design the laser modules that will be built in the Phase II. The proposed affordable, diode-pumped, solid-state laser module has commercial applications in a variety of material processing applications.
