Schematic setup of Trestles LH10-fs/CW laser system with
built-in pump laser
Del Mar Photonics supply Trestles lasers as stand alone system, or as a
one-box system with built-in DPSS pump laser.
The price of the system with DPSS pump depends on required output power.
The standard tuning elements indicated below are used in CW Ti:Sapphire
lasers such as
Trestles CW or Trestles fs/CW.
Those elements are also sold separately as standrad items or as a custom made
components.
1) Thick etalon -

Thickness - 3 mm, diameter - 20 mm. Surface quality: Ð=1-2, N<1, ΔN<0.1,
λ/10, plane parallelism better than 10''. Thickness accuracy 5 um.
2) Thin etalon -
request a quote
Thickness - 200 um, diameter - 15 mm. Surface quality: Ð=1-2, N<1, ΔN<0.1,
λ/10, plane parallelism better than 10''. Thickness accuracy 5 um.
We use a 3-plate assembled BRF (Lyot filter) with adjustable motorized mount
(see attached drawing).
Total losses introduced into the cavity by the filter are 5% of the laser’s
output power. The FSR is defined by the thinnest plate and equals to around -
1.3*1014 Hz, while the maximum width is controlled by the thickest
plate and equals to approx. 3.1*1012 Hz.
Dimensions of plate assembly ('filter' in the picture): dia 44.5 mm, t=13.5 mm.
It should be properly aligned (Brewster to the beam) and rotated by some
rotating mount around its axis to provide wavelength tuning.
Third and Forth Harmonic Generator for Ti:Sapphire lasers:
Three Case studies
Customer inquiry:
We have about 1 W across the range 780nm to 920 nm. We are interested mostly
in tunability in the range 240-300nm. Pulse width is not very > important. If a
(third + fourth) HG exists in one model, that would be great. Also it would be
good for us to have several wavelength available at the same time, i.e.
fundamental and harmonics.
I want to use this system for a photoemission microscope, and my first interest
is in the tuning capability. The second interest is in building up a
pump-and-probe system using the fundamental or 2nd harmonic as a pump beam and
the third harmonic as probe. Do you have suggestions for the delay-line?
Answer:
We can offer our multiharmonic (SH, TH) generator unit. The simultaneous output
will have around 10% (100 mW) of your input power in fundamental and each of
harmonics (10% fundamental, 10% second and 10% third). Each harmonic has its own
output (see attachment). The tuning range will be 260-300 nm for TH with your
input tuning range.
The FH system will produce 205-230 nm radiation out of your laser (780-920)
Customer inquiry:
I'm interested in the 3^rd harmonic generator for an amplified Ti:sapphire laser.
What is the maximum pulse energy? The system is a Coherent regenerative
amplifier (RegA 9000) that produces 750 mW at a repetition rate of 100 kHz,
which is a pulse energy of 7.5 microjoules in 50 femtoseconds. The beam diameter
is 2.7 mm.
We have tried to use a Coherent 9300 harmonic system, but it is designed for
oscillator energies of nanojoules, so it is too tightly focused on the crystal
and generates white light.
Answer:
Please find enclosed the quotation for the TH generator along with
the drawing. Please note that since the unit is non-standard the dimensions
may be extended by +100 mm in length and +50 mm in width.
ATsG800 Third Harmonic Generator
Second and third harmonic outputs
Input wavelength for TH – 750-900 nm
Input wavelength for SH – 710-960 nm
Input pulse width - >20 fs
Conversion efficiency for TH – 7-8% (depends on input
parameters)
Conversion efficiency for SH – >30% (depends on input
parameters)
Pulse broadening - <150 fs Input pulse energy – 8 μJ

Del Mar Photonics:
We can offer about 7-8% efficiency, the version for 8 uJ will be non-standard.
Please find enclosed
the quotation for the TH generator along with
the drawing. Please note that since the unit is non-standard the dimensions may
be extended by +100 mm in length and +50 mm in width.
Third harmonic generator (THG) is developed for frequency doubling and
tripling of Ti-Sa amplifier radiation (λ=780-820 nm). Device is based on second
harmonic generation (SHG) and sum-frequency generation (SFG) techniques and
provides stable radiation in fs scale. TH generator is developed for high
conversion efficiency.

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.

Frequency-stabilized CW
single-frequency ring Dye laser DYE-SF-007 pumped by DPSS DMPLH laser installed
in the brand new group of Dr. Dajun Wang at the The Chinese University of Hong
Kong.
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,
Bose-Einstein condensate and quantum degenerate Fermi gas and High resolution
spectroscopy
Del Mar Photonics continuously expands its components
portfolio.
