The construction of the Nano
series of PIV laser systems
is extremely robust. They have
been developed as industrial
tools that can be handled without
worry of misalignment or damage.
The PIV head is formed by an
aluminium gauge-plate onto
which two standard Nano-series
heads are mounted. The output
beams are combined by dielectric
polarisers and then frequency
doubled, and if desired can
be frequency tripled, quadrupled
or quintupled.
Many of the Nano PIV systems
are powered by a single power
supply unit, making the overall
package both powerful and portable.
There are two twin power supplies
available, the LPU450-PIV and
the LPU550-PIV, the latter
allowing outputs of 200mJ at
532nm at 15Hz from each laser.
The laser system is controlled
via a remote controller. All
trigger and synchronisation
signals are TTL compatible,
and each laser is controllable
entirely independently.
All Nano laser heads have
a verified electronic intra-cavity
safety shutter as standard,
which ensures that the lasers
cannot be started with the
shutter open – an important
safety feature. |
