Matrix 355-nm Lasers
Dec 2007
Coherent Inc.Request Info
SANTA CLARA, Calif., Dec. 5, 2007 -- Coherent Inc. said the two new models in its Matrix 355 series of solid-state lasers are economical, air-cooled 355-nm systems for OEM integration that feature Matrix technology previously available only with infrared output.

According to Coherent, these lasers 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 1 W of average power at a 60-kHz pulse repetition rate, and the Matrix 355-2-20 delivers 2 W at 20 kHz. Both lasers are RoHS compliant and have warranties.

Before the introduction of these 355-nm lasers, Matrix technology was available only with infrared output. Now, these new maintenance-free lasers use that design with ultraviolet-compatible materials in the laser head, plus unique multipass harmonics, to deliver long lifetime, low pulse-to-pulse noise stability, excellent thermal pointing stability and high beam quality, according to Coherent.

The output characteristics of Matrix 355 lasers make them suitable for precision applications in materials processing and microelectronics, such as stereolithography (rapid prototyping), LCD/FPD titling, memory repair, thin-film processing, precision marking and semiconductor scribing. In all of these applications, the company said, the lasers provide complete control over pulse energy and timing, including the ability to hold the pulse energy constant as the repetition rate is varied.

With respect to television, that part of a color television circuit that combines the I, Q and Y signals, and changes them into single red, green and blue signals applied to the picture-tube grids.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
A method of creating real three-dimensional models by using lasers driven by CAD software. In contrast to the normal practice of removing material, this process polymerizes a liquid to quickly produce shapes that are untouched by human hands or cutting tools. Also known as three-dimensional imaging and three-dimensional modeling.
