Intense Ltd., developer of next generation semiconductor lasers, systems and solutions, today announced the 600W Mini stack, the newest member of the Hermes family of high power QCW stacked arrays. The 600W Mini Stack is an ultra compact 600W QCW stack with an emission area of less than 3mm x 3mm. A high brightness stack, it generates output in the range of 7.6 kW/cm2. The design is built in standard wavelengths of 808 and 940 nm. Custom wavelengths, including multicolor options, are available on request.
The Mini stack offers 50% higher optical power density than some 2kW stacks that use standard bar technology, stated Kevin Laughlin, Chief Commercial Officer at Intense Ltd. This, combined with a compact footprint and small emission area, makes the Mini stack the ideal candidate for high power end pumping of DPSS laser sources. Its ultra compact form factor and high optical power density offer a real opportunity to reduce size and cost, and dramatically improve system operating efficiency for solid state laser manufacturers currently using flash lamps or standard diode bar pump technology.
The standard 600W Mini stack is offered for operating conditions to 60 degrees C. High temperature versions of most Hermes bars and stacks, covering operating ranges from 70 to 130 degrees C, are available. Power levels and emission areas can also be custom designed to meet specific needs of OEM customers.
The 600W Mini stack was designed with the defense market in mind, continued Laughlin. Defense customers are always looking to reduce the footprint/weight ratio, and improve battery life and system performance, particularly under harsh conditions. The 600W Mini is an extremely compact, ruggedized end pump diode array solution with a very bright future in front of it.
The 600W Mini stack and all Hermes bars and stacked arrays incorporate Intense's patented Quantum Well Intermixing (QWI) technology. This increases the brightness and reliability of the lasers while dramatically reducing instances of catastrophic optical damage (COMD). The entire line of Hermes QCW bars and stacks are assembled using AuSn hard solder and designed for a wide range of aerospace, defense and industrial applications.
