AOTF Infrared Spectrometer
Del Mar Photonics offer a handheld
infrared spectrometer based on the
acousto-optic tunable filter (AOTF). This instrument is about the size and
weight of a video camera, and can be battery operated. This unique, patented
device is all solid-state with no moving parts. It has been sold for a wide
variety of applications such as liquid fuel analysis, pharmaceutical analysis,
gas monitoring and
Miniature AOTF infrared spectrometer uses
a crystal of tellurium dioxide to scan the wavelength. Light from a light source enters
the crystal, and is diffracted into specific wavelengths. These wavelengths are
determined by the frequency of the electrical input to the crystal. Since there
are no moving parts, the wavelength scanning can be extremely fast. In addition,
specific wavelengths can be chosen by software according to the required algorithm, and therefore can be modified without changing the
hardware. After the infrared radiation reflects off of the sample, it is
converted into an electrical signal by the detector and analyzed by the
computer. Del Mar Photonics is looking for international distributors for
RAVEN - AOTF IR spectrometer for plastic identification and for variety of
scientific and industrial collaborations to explore futher commercial potential
of AOTF technology.

Future nanostructures and biological nanosystems will take
advantage not only of the small dimensions of the objects but of the
specific way of interaction between nano-objects. The interactions
of building blocks within these nanosystems will be studied and optimized on
femtosecond time scale - says Sergey Egorov, President and CEO of Del Mar
Photonics, Inc. Thus we put a lot of our efforts and resources into the
development of new Ultrafast
Dynamics Tools such as our Femtosecond Transient Absorption Measurements

create a new photovoltaic system that will efficiently convert photon energy
in charge separation, or build a molecular complex that will dump photon energy
into local heat to kill cancer cells, or create a new fluorescent probe for

DYE-SF-077 features exceptionally narrow generation line width, which
amounts to less than 100 kHz. DYE-SF-077 sets new standard for generation
line width of commercial lasers. Prior to this model, the narrowest line-width
of commercial dye lasers was as broad as 500 kHz - 1 MHz. It is necessary to
note that the 100-kHz line-width is achieved in DYE-SF-077 without the use of an
acousto-optical modulator, which, as a rule, complicates the design and
introduces additional losses. A specially designed ultra-fast PZT is used for
efficient suppression of radiation frequency fluctuations in a broad frequency
range. DYE-SF-077 will be used in resaerch of Ultracold polar molecules,

Compact Pulsed Nd:YAG Lasers
Del Mar Photonics offers compact pulse Nd:YAG lasers with excellent beam
quality, high energy/efficiency and possibility of efficient PRR changes with no
significant degradation of the output beam parameters. No matter how you may
wish to use it — as a standalone laser or as a pump source for tunable lasers
and OPO — the Del Mar Photonics LQ529 laser provides a combination of high
operation parameters, reliability and reasonable price which could not be
Ring cavity design of the LQ529 oscillator ensures perfect balance of energy,
beam quality and reliability.
Excellent Beam Quality
Compensation of depolarization over the Nd:YAG rod crosssection together with
traditional advantages of ring cavities ensure excellent beam profile. Unique
optical design of the LQ529 not only makes losses and distortions caused by
induced birefringence almost negligible, but also minimizes thermal lensing
effect. The above allows the user to vary pulse repetition rate within a wide
range and requires no further cavity alignment to preserve high beam quality and
LQ529 lasers provide smooth beam profile for all harmonics.
Figures show beam profile at 355nm/50Hz.
This constitutes a great advantage over lasers using expensive and
difficult to align Gaussian optics and thus demanding realignment and sometimes
even replacement of optical components in order to avoid dramatic worsening of
their output parameters if pulse repetition rate (PRR) has been changed.
Energy Through Efficiency
One of the main reasons for moderate efficiency of conventional Q-switched
lasers is birefringence induced in the Nd:YAG rod leading to depolarization of
laser output. Each time the beam passes through the cavity, depolarized lasing
is filtered by various polarization units and is dropped out of the cavity that
leads to decrease in laser operation efficiency. Optical design of the LQ529
laser cavity allows to practically eliminate energy losses caused by
depolarization and provides laser energy output with more than 2% wall-plug
efficiency of a laser system (total electrical-to-optical power efficiency). Such a high efficiency
allows the LQ529 to provide up to 600mJ output energy without using an amplifier.
Single rod and single flash lamp design is the determining factor for reduction
of the laser price and maintenance costs.
Supplementing the basic model with a onepass amplifier allows to provide up to
1500mJ output energy
in the fundamental (model LQ929) while preserving all the advantages of the
A power supply unit and a self-contained
water-to-air cooling system are integrated

and large LCD makes laser operating much
Stable And Reliable Operation
One of the obvious advantages of the laser is its absolute mechanical stability
Pulse-to-pulse energy stability of LQ529C laser at 355nm (THG)
All optical components are mounted on the rigid optical bench which is
mechanically and thermally isolated from the laser housing. This ensures
exceptional alignment stability even under toughest conditions of
transportation and operation. All nonlinear crystals and Pockels cell are
temperature stabilized. Optical bench with cavity components is also
temperaturestabilized. High-precision termostabilization ensures minimal
pulsetopulse and longterm instability. Heating of optical components to the
temperature exceeding ambient totally eliminates any risk of condensation. This
feature along with dustproof housing protects the optics from damage and
minimizes the necessity in service. It should also be noted that the LQ529 laser
design eliminates the necessity of any laser alignments after flashlamp replacement, while the replacement procedure itself takes less than 10
All Harmonics Available
All harmonic options — 532nm, 355nm, 266nm and 213nm — are available as
High-efficiency Harmonic Generators can be either built-in (except for the FiHG)
or supplied as separate units upon the customer’s request. For this reason all
the harmonics can be ordered with the laser or at later date.
Compact Intelligent Power Supply
A power supply unit and a selfcontained watertoair cooling system are
integrated into one compact package. Compact size and closed loop cooling system
which requires no external water, allow to place the power supply under the
optical bench or wherever convenient. Computer control using the optional RS232
interface allows integration into laboratory or industrial automated systems.
Highpower cooling system and automatic temperature control with 0.5°C precision
ensure stable laser operation at up to 30°C ambient temperature. A heater built
into the cooling system reduces warm-up time to several minutes even at 15°C

Meets almost all major requirements made to lasers for industry applications.
Design features provide a highest reliability and low demands to operation
conditions. Low operating cost, fast and simple service are also significant
factors for industrial applications of the LQ529 Laser.
Mobile laser systems
Unique mechanical rigidity and resistance to mis-alignments, low electricity
consumption and air cooling make the LQ529 an ideal laser source for various
mobile measuring and monitoring systems which may be installed on any transport
means. Dust protected laser head design ensures long-term reliable operation of
laser optical components even in field conditions.
