Coherent debuts high-power AVIA 355-28 UV laser for micromachining

Coherent Inc. (Santa Clara, CA) has extended its industry accepted family of AVIA™ micromachining lasers with a new model that reportedly offers the highest power commercially available at its wavelength and repetition rate. Specifically, the new AVIA 355-28 delivers 28 Watts of output at 355 nm (at 110 kHz). This high power and high repetition rate translates directly into increased throughput for a variety of micromachining applications, as well as lower cost per part.

In addition to higher power, the AVIA 355-28 offers several features specifically designed to enhance its processing capabilities and minimize long term cost of ownership. These include PosiLock, which is Coherent's proprietary technology for achieving highly repeatable spot positioning at the work surface, PulseEQ, which provides constant pulse energy across a wide range of rapidly varying pulse repetition rates, and an automated harmonic crystal shifter to maintain constant output power over the entire lifetime of the laser.

The AVIA 355-28 is targeted at a wide range of demanding, high-throughput micromachining applications in semiconductor fabrication and packaging, as well as solar cell production. Typical examples include dicing and scribing of silicon wafers and low-k semiconductors, via-hole drilling in printed circuit boards and flip chips, and micromachining medical disposables.

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.
