GSI Lumonics Introduces Updated JK700TR Series of Pulsed Laser Processing Systems


FARMINGTON HILLS, MI & RUGBY, ENGLAND, June 2002 -GSI Lumonics Inc. (Nasdaq: GSLI and TSE: LSI) has introduced a new generation of its highly successful JK700TR series of pulsed Nd:YAG laser systems. Spanning a range of power levels, the new JK700TR series lasers build on three decades of experience in industrial lasers to provide the brightest, highest quality beams with the latest technology for class leading performance. Highly versatile, the JK700TR series lasers are used in a variety of applications for welding, drilling, and cutting and provide the best overall cost of ownership for users of pulsed lasers.

The new JK700TR series lasers include GSI Lumonics' patented TR Technology, which the company previously pioneered and has been field-proven in the model JK704TR drilling laser. TR Technology uses a twin-rod oscillator design to increase efficiency and decrease heat input into the laser rods. It provides the highest beam quality for faster processing, longer working distances, and smaller spot sizes, all of which translate into tangible end-user benefits.

In addition, the new systems include a patented power supply which enables higher peak powers - up to 10kW - and which enable pulse shaping, a technique which allows a user to optimize the laser pulses' peak power, shape, and duration to suit process needs, increasing yields and reducing cost.

The systems also include more ruggedized, easy-to-install Luminator fiber optic cabling, updated optics, and an optional graphical user interface for simplified access to all system functionality and status. Time-share and energy-share options are available with the system.

"The JK700 series laser family, first introduced in 1986, has been carefully refined and tested over time," explained William LeBlanc, General Manager of the Rugby, England facility where the JK lasers are manufactured. "This latest generation of the lasers extends the JK heritage as the industry's most reliable and proven workhorse pulsed lasers. They include key proprietary technologies for outstanding flexibility in applications ranging from medical device manufacturing through automotive parts manufacturing."

GSI Lumonics Inc. brings laser-based automated advanced manufacturing systems and components to leading industrial companies worldwide. The Company supplies products and services to the semiconductor, electronics and industrial manufacturing markets, as well as precision optics for telecommunications. GSI Lumonics' common shares are listed on Nasdaq (GSLI) and The Toronto Stock Exchange (LSI). For more information on GSI Lumonics, please visit www.gsilumonics.com.
