The company has extended its portfolio with a new laser that has significant high power.

Coherent has extended its industry
accepted family of AVIA micro machining 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
micro machining 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 minimise 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 micro machining 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 micro machining medical disposables.
