MATRIX™ 355 series solid-state lasers


The new MATRIX™ 355 series solid-state lasers from Coherent, Inc. (Santa Clara, CA) (Nasdaq: COHR) are economical, air-cooled systems for OEM integration. They combine consistent operation with high performance (high beam quality, low noise) and exceptional lifetime. Two models are currently offered: the MATRIX 355-1-60 delivers over 1W of average power at a 60 kHz pulse repetition rate, and the MATRIX 355-2-20 delivers 2W at 20 kHz. Both lasers are fully RoHS compliant and backed by industry-leading warranty terms. MATRIX lasers offer the highest possible performance/cost ratio. They feature PermAlign™ (soldered) component mounting technology, robotic assembly methods, and proven, long-lived components such as AAA™ (Aluminum-free Active Area) pump diodes. Before the launch of these new 355 nm lasers, MATRIX technology was available only with infrared output. Now, these new maintenance-free lasers use that successful design with UV compatible materials in the laser head, plus unique multi-pass harmonics, to deliver long lifetime, the industry’s lowest pulse-to-pulse noise stability, excellent thermal pointing stability, and high beam quality. The output characteristics of MATRIX 355 lasers make them particularly suitable for precision applications in materials processing and micro-electronics, such as stereolithography (rapid prototyping), LCD/FPD titling, memory repair, thin film processing, precision marking and semiconductor scribing. In all of these applications, they provide complete control over pulse energy and timing, including the ability to hold the pulse energy constant as the repetition rate is varied.
