Santa Clara, Calif. – Coherent Inc. (Santa Clara, CA) (Nasdaq: COHR) has extended its industry accepted family of AVIA™ micromachining lasers with a new model that 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.
