Lasers offer longer working lives
The Hermes stacks degrade by less than 5% over two 10E8 shots as compared to competitive products that degrade by 20% or more.
Intense has released an expansion of the Hermes family of high-power QCW (quasi-continuous wave) arrays The newest lasers, now qualified to military standards, combine high reliability with robust, modular packaging in a standard wavelength of 808nm with power levels up to 900W

Intense is pleased to announce Inslam, a new family of laser diode modules designed specifically for defence and digital printing applications.
Lasers are designed for high power uses
Intense will unveil a new family of high power laser diodes at SPIE's Photonics West conference, 23rd to 25th January 2007, in San Jose, California.
The Hermes stacks degrade by less than 5% over two 10E8 shots as compared to competitive products that degrade by 20% or more.
This means the Hermes products provide significantly longer lifetimes, ultimately reducing costs for OEM developers.
The Hermes stacked arrays are "QWI-enabled", developed using Intense's Quantum Well Intermixing (QWI) technology, which produces superior power, brightness and reliability for a wide range of demanding applications, such as rangefinding, target designation and pumping.

Hermes high power laser products are designed for use in industrial, medical, defence and aerospace applications where high brightness and optical conversion efficiency are needed.
Driver takes control of high-power lasers
Laser driver system is designed for current control and temperature compensation of high power free space or fibred visible laser components.
Professor John Marsh, CTO at Intense said "Hermes high-power lasers are based on a compact, modular architecture that delivers high brightness and high efficiency".
"This improves overall performance of the OEM system, reduces energy consumption and allows for development of innovative optical products".
The Hermes QCW stacked arrays are available as vertically or horizontally stacked assemblies of up to 10 bars, with lensed and unlensed options.
Standard configurations include a Hermes 360W four-bar stacked array, with a minimum 360W peak output power.
The Hermes 540W six-bar stacked array has a minimum 540 W peak output power while the Hermes 720W is an eight-bar stacked array, with a minimum 720W peak output power and the Hermes 900W version is a 10-bar stacked array with a minimum 900W peak output power.
Other wavelengths are available on request.
Developed using a highly robust hard solder process for stack assembly, Hermes 900W, the 10-bar stacked array, has been qualified to military standard MIL-STD-810F, Methods 501.4, 503.4, 514.5 and 516.5.
Hermes QWI-enabled lasers are based on Intense's Quantum Well Intermixing (QWI) process.
This process increases the quantum well band-gap of a semiconductor laser in a controlled and very precise manner, such that active and passive sections can be created in the same laser cavity.
Passive nonabsorbing mirrors (NAMs) are created at the facet regions of the cavities to avoid catastrophic optical mirror damage (COMD), a problem frequently encountered in typical laser devices.
The end result is a high-performance laser that can operate at high optical power and brightness with exceptional reliability.
