UV Laser produces 1.5 W at repetition rate of 70 kHz.February 20, 2009 -
Utilizing components such as aluminum free active area pump diodes and multi-pass harmonics generation technology, MATRIX 355-1.5-70 exhibits less than 2% rms, and beam quality of M2 < 1.3. Unit is suited for stereolithography, enabling step from rapid prototyping to rapid manufacturing, as well as for scribing sapphire substrates in GaN/InGaN based LED production. Other applications include thin film processing, memory repair, cold marking, and semiconductor scribing.

New MATRIX UV Laser for High-Throughput Applications
Santa Clara, Calif., January 27, 2009 - Coherent Inc. (Santa Clara, CA) (Nasdaq: COHR) has expanded its family of MATRIX(TM) lasers with a new ultraviolet model optimized to produce 1.5 Watts at a high repetition rate of 70 kHz, in order to support high-throughput applications. In addition to high speed, the MATRIX 355-1.5-70 delivers enhanced precision by enabling complete control over pulse energy and timing from the first to the last pulse. For example, the pulse energy can be held constant as the repetition rate is varied. Moreover, the cost/performance ratio of this new laser is specifically targeted at industrial processing applications where cost per processed unit is just as important as reliable operation and stable parameters over time.
All MATRIX lasers are fully RoHS compliant and backed by an 18 month/10,000 hour warranty. They utilize Coherent's unique PermAlign(TM) (soldered) component mounting technology, robotic assembly methods and proven, long-lived components such as Aluminum Free Active Area (AAA(TM)) pump diodes. Together with unique multi-pass harmonics generation technology, this results in long laser lifetime, the industry's lowest pulse-to-pulse noise (typically <2% rms), outstanding pointing stability (max. ?15 µrad/°C), and high beam quality (M2 <1.3).
MATRIX 355-1.5.70 is ideally suited for stereolithography, enabling the step from rapid prototyping to rapid manufacturing, as well as for scribing sapphire substrates in GaN/InGaN based LED production. Other applications include thin film processing, memory repair, cold marking and semiconductor scribing.
Founded in 1966, Coherent, Inc. is a Russell 2000 Index company and a world leader in providing laser-based solutions to the commercial and scientific research markets. For more information about Coherent, including product and financial updates, visit our website at http://www.Coherent.com.
