Alfalight Receives $1.36 Million Army Contract to Develop Advanced 1 kW Laser Diode Pump Source

Army Research Laboratory Award Extends Successful Programs to Enable Pumps for Brighter, More Cost-Effective and Reliable High-Power Solid State Lasers

Alfalight, Inc., a leading manufacturer of highly efficient high-power diode lasers, announced today that it has received a $1.36 million contract from the Army Research Laboratory (ARL) in Adelphi, MD. This 12-month program, entitled “High Brightness Diode Sources II” (HiBriDS II), will enable Alfalight to extend the success of previous programs to create solid state laser diode pump sources with higher brightness and reliability than current technology can provide. The objective of the program is to demonstrate 1 kW of 975 nm narrowband, wavelength-locked diode laser light coupled into a 600 µm, 0.22 NA fiber.

Alfalight's past performance in DARPA's ADHELS (Architecture for Diode High Energy Laser Systems) and ARL's HiBriDS programs has allowed us to push both the spatial and the spectral brightness of pump diodes by implementing brightness enhancement and wavelength-stabilization technologies,” said Manoj Kanskar, vice president of Research and Development at Alfalight. “The extended scope of HiBriDS II will allow us to make a significant improvement to the brightness and power of cost- effective kilowatt-class pump modules.”

The new design will require less-demanding manufacturing tolerances and fewer optical components to scale power, allowing resultant products to be more cost-effective and robust compared to fiber-coupled bars. Products resulting from the HiBriDS II program will also combine Alfalight's integrated wavelength stabilization technology, high power-conversion efficiency, and proven packaging expertise to enable products requiring only industrial water cooling, rather than micro-channel cooling. Applications will include defense systems, commercial fiber laser pumping, and solid-state laser pumping as well as direct-diode materials processing.
