The LEXEL™
AC-530 Resonator Stabilizer Overview
The patented LEXEL™
AC-530 Resonator Stabilizer Solid
Invar Resonator Structure has long been
recognized as one of the most mechanically
and thermally stable optical resonators
available commercially for Ion Lasers.
It has been adapted to our LEXEL™
SHG laser operation
with great success, as well as a being used
as a stable platform for generating high
power single frequencies.
LEXEL™ Lasers,
when operated in standard laboratory
conditions, at fixed power levels, produce
extremely stable power and beam-pointing
stability for extended periods of time.
The complexity of the resonator requires
that all optical and structural components
of the optical resonator be held at the same
relative temperature, if long-term
stability is to be maintained. All Lasers
routinely achieve this level of stability if
the laser is running continuously for
several hours.
However, when a stable,
warmed-up, laser is shut off, and then
restarted under “cold” conditions, it may
take some time for all the resonator
components to acquire the former thermal
conditions to continue the operation at the
previously stable level. Most operators
become impatient with this long warm up time
until the former thermal conditions are
achieved. Thankfully, our LEXEL™
AC 530 solves this problem!
The latest LEXEL™ Lasers can be equipped with
a new optional feature called a “AC
530 Resonator
Stabilizer”. The purpose of this Stabilizer
is to allow the laser to be restarted at a
stable level (with a relatively short
“warm-up”) after an extended “OFF” period,
without having to wait several hours for the
optical resonator to acquire the former
thermal conditions.
The use of the LEXEL™ AC 530 Resonator
Stabilizer typically allows stable operation
to be resumed within only 15 to 20 minutes
following an over night shutdown, not the
usual 60 to 120 minutes (or more) seen with
other systems.
The LEXEL™ AC 530 Resonator
Stabilizer
shortens the warm up time for your Laser, as
well as it also reduces the
long term beam pointing by increasing the
resonator stability to allow for extended
periods of Single Frequency Operation "Mode
Hop" free. It also provides
for hours of SHG generated
Deep UV operation.
