Overview
Today, Diode Pumped Solid State (DPSS) lasers are being
used in a growing number of industrial OEM and research applications
ranging from biomedical to materials and spectroscopy to laser
pumping.
Ongoing advances in Diode Pumped Solid State (DPSS) optical
cavity designs are driving the need for highly optimized
diode controllers. In addition to driving the diode and crystal
TECs, today’s controllers are required to optimize the relationships
between system output, laser diode current, laser diode temperature
and crystal temperature. In the past, this optimization was
done manually and it required significant production time
to measure the parameters and adjust numerous variables.
VueMetrix microprocessor-based controllers are designed to
support optimization routines that automate and manage multi-variable
systems. Optional memory is available and allows for a wide
variety of routines that greatly improve DPSS laser system
manufacture and operation. The result is reduced manufacturing
time, improved reliability and higher quality end products.
This offers you the potential for significant cost savings
during manufacturing and better longterm stability of the DPSS
laser. Field upgradeable firmware gives you the flexibility
to add new features for your customers. VueMetrix specializes
in developing OEM controllers with single or multiple TECs
and a variety of diode currents. These fully integrated controllers
are available as an embeddable PC board, a minimally packaged
OEM unit, or as a CDRH compatible standalone unit with a laser
system key switch.
VueMetrix has an extensive library of hardware and software
designs available for all types of laser diode control. With
our modular design system, we can help you to develop your
controller quickly and cost effectively, yet customize it for
your exact needs.
