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.
High power lasers use quantum well intermixing
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.
The process allows for the monolithic integration of a large number of high power, individually addressable, single mode lasers on one chip.
This provides for the precise delivery of optical energy, enabling the highest accuracy and speed from the next generation of military rangefinders and illuminators, as well as digital presses.
"Manufacturers of precision equipment are demanding increased laser power and smaller form factors in order to provide higher accuracy and speed, as well as lower costs," stated Professor John Marsh, PhD, CTO at Intense and developer of the company's patented QWI design process.

Laser diodes offer 200mW of kink-free power
Intense, the developer of next generation semiconductor lasers, today announced the Intense-HPD series 6100, 980nm high power single emitter laser diodes.
"The exceptional uniformity and beam control of each laser element in our revolutionary new modules enable increased spatial brightness to be achieved at a cost effective price".
"In addition, the compactness of the lasers provides the flexibility designers need to upgrade the functionality of existing systems".
"In one semiconductor package, we are able to drive down laser-based equipment costs and bring unrivalled performance to a range of applications".
Each Inslam module contains individually addressable laser arrays with 10 to 100 emitters that operate at wavelengths within the 808 to 980nm range.
Single mode and multimode configurations are available.
The modules are effective with an individual pitch as low as 70um and power range of 30 to 200mW.
The reliability of Inslam is outstanding, with data well in excess of 10,000 operating hours.
Each module includes the laser array and, if required, the drive electronics, optical monitoring, and micro and/or macro optics.
This means a single, compact unit can replace a much larger traditional subsystem.
The Inslam devices are based on Intense's new 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 non-absorbing 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 with exceptional reliability.
NAMs bring additional advantages to many applications, including defence and digital printing, since the facet regions remain relatively cold during operation.
This produces an exceptionally well controlled single mode beam in terms of spot size and pointing stability.
The exceptional uniformity and beam control of each laser element in the array result in very high resolution imaging.
The INSlam family of laser diode modules are supplied in a compact package that includes optical, electronic, and thermal management components.
