We develop and produce Single
Frequency DPSS lasers at Any wavelength from NIR to UV using a single
engineering platform based on our proprietary patented BRaMMS DPSS Laser
technology demanding applications in:
l Leading
edge research
l Life
Sciences, BioMed,
l Semicon,
l Environmental
Metrology, etc.
Using the BRaMMS laser technology we can offer any wavelength within spectrum
range:
l from
IR (around 2�m) to through deep UV (<200nm)
l from
our range of DPSS lasers operating in the CW Single Frequency regime. This is
unique for a single platform laser technology.
All products feature laser cavity feedback locked Single Longitudinal Mode CW
performance with no lock loss and mode hops during 100s of hours of nonstop
operation. The excellent beam quality with M2 <1.05 emerges from the smallest
footprint and at the lowest power consumption for given output, with noise
figure as low as < 0.1%rms (10Hz-10MHz).
Benefits of our laser design include:
l Up
to ten times higher conversion efficiency
l Power
scalability without water cooling
l No
mode beating & associated high frequency noise, which often limits applicability
l The
longest coherence length of over 100m, effectively the path difference over
which lasers can interfere.
BRaMMS DPSS Laser technology by us is the company�s proprietary pioneering
technology platform.
It utilises the spectrum discriminatory feature of a Michelson interferometer
setup within a spectral range preselected by VBG (Volume Bragg Grating). This
suppresses all but one lasing longitudinal mode within a laser cavity. Hence �
Bragg Range Michelson Mode Selector (BRaMMS).
Due to significantly lower power consumption for any required output and the
resulting simplified thermal management, the BRaMMS laser technology provides up
to 10 times wider range of output power scalability from the smallest footprint.
We advance this
technology via three main engineering lines:
1. BRaMMS � Solo-XXXX/XXXX, covering spectrum range 700nm-2000nm by the
generation at the fundamental wavelength;
2. BRaMMS � Duetto-XXX/XXXX, covering spectrum range 350nm -780nm by an
intracavity second harmonic generation;
3. BRaMMS � Quartetto-XXX/XXXX, covering spectrum range 200nm � 380nm by an
intracavity fourth harmonic generation.
BRaMMS Laser Technology provides new wavelengths previously unattainable by DPSS
lasers in UV, Visible and Near IR.

Our technology is able to displace bulky and inefficient gas lasers like
argon-ion or helium cadmium lasers, dinosaurs of the laser industry. Our Single
Frequency DPSS lasers are compact, reliable and long life systems, in demand for
many cutting edge research and industrial applications, for example:
l life
sciences instrumentation,
l semiconductor
wafer metrology,
l holographic
imaging,
l particle

l avionic
technologies�
Using the BRaMMS laser technology we can offer any wavelength within the
spectrum range from IR (around 2000nm) through deep UV (<200nm) from its range
of DPSS lasers operating in the CW Single Frequency regime.
Additionally, due to the significantly lower power consumption for any required
output and the resulting simplified thermal management, the BRaMMS laser
technology provides up to a 10 times wider range of output power scalability
from the smallest footprint. This opens up applications in portable and remotely
controlled systems and devices which until our products were available have
never before considered feasible.

Applications:
We are the only company to be able to configure Continuous Wave, Single
Frequency Lasers to uniquely emit at any wavelength covering the spectral range
from Near Infra-Red to Ultra-Violet from a single universal technology platform,
using proprietary patented BRaMMS technology.
The potential
applications range is vast:
l holographic
art to large scale structural analysis;
l from
pharmaceutical instrumentation to cutting edge particle trapping techniques;
l from
semiconductor wafer micro-processing to wind turbine power generation and
avionic technologies.
Our novel patented BRaMMS technology provides reliable, cost effective, compact
all-solid-state and class leading solutions for both well established and
currently unavailable, but demanded, wavelengths. This opens up applications in
portable and remotely controlled systems and devices, which have been never
before considered feasible.
The newest generation of ultra compact, air cooled all solid state products is a
new choice on the current deep UV spectrum market and a strong competitor to the
pulsed laser technologies traditionally offered by large excimer UV gas lasers
and water cooled frequency tripled/quadrupled Nd:YAG systems.
Let�s look at our newer laser with wavelength of 515nm. This laser has a
scalable output power up to several Watts, and is a compact, reliable and long
life plug-and-play replacement for the bulky and inefficient argon-ion gas laser
with the same green emission.
The new laser will feature optimised second harmonic generation of the diode
pumped ytterbium doped YAG (Yb:YAG) laser at 1030nm using our novel patented
BRaMMS technology.
Argon ion lasers have been around since the end of the 1960�s and found broad
applications in areas such as holography, printing, digital imaging,
non-destructive testing including semiconductor inspection, spectroscopy,
optical pumping, confocal microscopy, flow cytometry, DNA sequencers, compact
disc and DVD mastering, photomask direct imaging, printed circuit board direct
imaging, and precision optics inspection. However, they suffer disadvantages of
being bulky (high power versions are several meters long) and inefficient (a 1W
single frequency green laser has an efficiency of 0.01% requiring a large 10kW
power supply with commensurate water cooling).
Benefits of our laser design include up to several orders of magnitude higher
conversion efficiency, giving them unique output power scalability while
eliminating the need for water cooling, a lack of mode beating and associated
high frequency noise which often limits applicability, and the longest coherence
length, over 100m, effectively the path difference over which lasers can
interfere.
