Pismo pulse picker
The Pismo pulse picker systems is as a pulse gating system that lets single
pulses or group of subsequent pulses from a femtosecond or picosecond pulse
train pass through the system, and stops other radiation. The system is
perfectly suitable for most commercial femtosecond oscillators and
amplifiers.
The system can pick either single pulses, shoot bursts (patterns of single
pulses) or pick group of subsequent pulses (wider square-shaped HV pulse
modification). HV pulse duration (i.e. gate open time) is 10 ns in the default
Pismo 8/1 model, but can be customized from 3 to 1250 ns upon request or made
variable. The frequency of the picked pulses starts with single shot to 1 kHz
for the basic model, and goes up to 100 kHz for the most advanced one.
The Pockels cell is supplied with a control unit that is capable of synching
to the optical pulse train via a built-in photodetector unit, while electric
trigger signal is also accepted. Two additional delay channels are available
for synching of other equipment to the pulse picker operation. Moreover, USB
connectivity and LabView-compatible drivers save a great deal of your time
on storing and recalling presets, and setting up some automated experimental
setups. One control unit is capable of driving of up to 3 Pockels cells, and
this comes handy in complex setups or contrast-improving schemes. The system
can also be modified to supply two HV pulses to one Pockels cell unit,
making it a 2-channel pulse picker system. This may be essential for
injection/ejection purposes when building a regenerative or multipass
amplifier system.

Reef femtosecond autocorrelators
The autocorrelation technique is the most common method used to determine
laser pulse width characteristics on a femtosecond time scale.
The basic optical configuration of the autocorrelator is similar to that of an
interferometer (Figure.1). An incoming pulse train is split into two beams of
equal intensity. An adjustable optical delay is inserted into one of the arms.
The two beams are then recombined within a nonlinear material (semiconductor)
for two photon absorption (TPA). The incident pulses directly generate a
nonlinear TPA photocurrent in the semiconductor, and the detection of this
photocurrent as a function of interferometer optical delay between the
interacting pulses yields the pulse autocorrelation function. The TPA process is
polarization-independent and non-phasematched, simplifying
alignment.
Reef-RT autocorrelator measures laser
pulse durations ranging from 20 femtoseconds to picosecond regime. It measures
pulse widths from both low energy, high repetition rate oscillators and high
energy, low repetition rate amplifiers. Compact control unit operates
autocorrelator head and optional spectrometer through on-screen menus.
Autocorrelation trace and spectrum can be displayed and analyzed on screen or
downloaded to remote computer.

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
plastic analysis.
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.

Hatteras-D
femtosecond transient absorption data acquisition system
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
the
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
system Hatteras. Whether you want to
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
FRET microscopy, understanding of internal dynamics on femtosecond time scale
is utterly important and requires advanced measurement techniques.Reserve a

Wavefront Sensors: ShaH Family
A family of ShaH wavefront sensors represents recent progress of Del Mar
Photonics in Shack-Hartmann-based technology. The performance of Shack-Hartmann
sensors greatly depends on the quality of the lenslet arrays used. Del Mar
Photonics. developed a proprietary process of lenslet manufacturing, ensuring
excellent quality of refractive lenslet arrays. The arrays can be AR coated on
both sides without interfering with the micro-lens surface accuracy. Another
advantage of the ShaH wavefront sensors is a highly optimized processing code.
This makes possible real-time processing of the sensor data at the rate
exceeding 1000 frames per second with a common PC. Due to utilizing low-level
programming of the video GPU, it is possible to output the wavefront data with a
resolution up to 512x512 pixels at a 500+ Hz frame rate. This mode is favorable
for controlling modern LCOS wavefront correctors.
The family of ShaH wavefront sensors includes several prototype models, starting
from low-cost ShaH-0620 suitable for teaching laboratory to a high-end
high-speed model, ShaH-03500. The latter utilizes a back-illuminated EM-gain CCD
sensor with cooling down to -100°C. This makes it possible to apply such a
wavefront sensor in astronomy, remote sensing, etc.

NARROW-BAND HOLOGRAPHIC FILTERS are intended for
suppression of powerful beams in research and in engineering, in particular, in laser
spectroscopy, and also for protection from blinding and damaging by laser radiation various photo
receiver devices and operator's eyes.
Unlike conventional interference filters, which are made by vacuum
evaporation techniques, holographic filters are fabricated by recording
interference patterns formed between two mutually coherent laser beams. Since all layers are recorded simultaneously within a thick stack, the
optical density of the notch filter is high and its spectral bandwidth
can be extremely narrow. Also, since the layering profile is sinusoidal
instead of square wave, holographic notch filters are free from
extraneous reflection bands and provide significantly higher laser
damage thresholds.
