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 - request a quote
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.

3) Birefringent filter BRF - request a quote

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.

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.

Femtosecond Transient Absorption Measurements system Hatteras 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
