High Power Laser Cooling

High Energy Laser (HEL) systems currently are being developed to extend the lethality and warfighting capabilities of the U.S. military. For viable deployment on tactical weapon platforms, the laser and cooling system must be compact, lightweight and reliable. The inherent inefficiencies of the laser components, large power requirements and high heat fluxes (500W/cm2) impose the primary obstacle facing HEL system deployment. Single-phase cooling approaches fail to address these challenges due extremely large coolant flow rates required for tight temperature control (+/- 2ºC) in laser devices. This traditional approach results in large, heavy cooling systems that are unattractive options for tactical platforms, such as a fighter jet, tank, or gunship. RINI Technologies' two-phase ESC is the only approach that results in dramatic reductions in the size, weight, and power (SWaP) of the laser-cooling loop enabling deployment of these systems.

BENEFITS:

• Enables Laser Deployment on Tactical Weapon Systems
• 10 to 20X Reduction in coolant flow rates over single-phase cooling systems
• 3 to 5X reduction in laser cooling system weight, volume & power

APPLICATIONS:

• High Brightness LDA's
• High Power VCSEL Arrays
• Solid-State Amplifiers and Oscillators Slabs / Crystals
• Cryogenic Solid State Laser Systems
