Quasi-Continuous Wave Stacks incorporate 808 nm laser bars.

Press Release Summary:



With emission area of 2.8 x 2.8 mm, Hermes 650 W Mini Stacks generate optical output in excess of 8 kW/cm² operating with ~300 µsec pulses. Standard units support operating temperatures from -40 to 70°C, while high-temperature versions handle temperatures up to 130°C. Fully qualified to military standard MIL-STD-810F, Mini Stacks are designed for handheld DPSS laser systems that require optimal performance under harsh conditions.

Intense Announces Next Generation QC Mini Stacks Maximize Operating Temperature Performance



Munich, Germany - Intense Ltd., developer of next generation semiconductor lasers, systems and solutions, today announced the next generation of the Hermes 650W Mini Stack at Laser World of Photonics in Munich, Hall 1, Booth 400 (IMM Photonics). The Mini Stack is an ultra-compact QCW stack offering maximum brightness at high operating temperatures. It incorporates new, high power 808nm laser bars designed for extending performance across a broad range of operating temperatures. A high brightness stack, it has an emission area of only 2.8mm x 2.8mm and generates an optical output in excess of 8 kW/cm2 operating with ~300µs pulses.

The 650W Mini Stack is designed for handheld DPSS laser systems, which require a reduced footprint/weight ratio, and improved battery life and system performance under harsh conditions. The Mini Stack has been fully qualified to military standard MIL-STD-810F, including storage temperature cycle (-57°C to 75°C), mechanical shock (>20K shots at 1000G), and more than 250k shots of continuous operation. The design can be produced for standard wavelengths of 808nm and 940nm. Custom wavelengths, including multicolor options, are available on request.

"The Mini Stack offers more than 50% higher optical power density than common 2kW stacks that use standard bar technology," stated Kevin Laughlin, Chief Commercial Officer, Intense Ltd. "The new bar designs offer improved performance over a wider range of operating temperatures. This, combined with a compact footprint and small emission area, makes the Mini Stack ideal for high power end pumping of DPSS laser sources."

The standard 650W Mini Stack supports operating temperatures from -40°C to 70°C. The new, high temperature versions of Intense's QCW bars and stacks, now meet output specifications at operating temperatures as high as 130°C. Power levels and emission areas can be custom designed for OEM requirements.

"The Mini Stack's ultra compact form factor and high optical power density offer a real opportunity to reduce size and cost," continued Laughlin. "They can dramatically improve system operating efficiency for solid state laser manufacturers currently using flash lamps or standard diode bar pump technology. As a direct result of our latest development efforts, Intense is now in the position to provide these stacks in combination with a whole new generation of laser bars designed to operate under the most challenging environmental conditions."

Quantum Well Intermixing

The entire Hermes product line will be on display at Laser World of Photonics, including the QCW bars the provide up to 400W of output power, and the QCW 1kW, 2kW, and 3KW stacks with 1kW, 2kW, and 3kW of output power, respectively. 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). These bars and stacks are assembled using AuSn hard solder and designed for a wide range of aerospace, defense and industrial applications.

Price & Delivery

The Hermes 650W Mini Stacks are available now in both standard and high temperature versions. Pricing is based on quantities ordered. Other wavelengths and configuration, including multicolor options, are available on request.
