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 achieved earlier.

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 output energy.



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 LQ529 model.


A power supply unit and a self-contained water-to-air cooling system are integrated into one compact package. Remote controller with the tactile panel and large LCD makes laser operating much more convenient.


Stable And Reliable Operation
One of the obvious advantages of the laser is its absolute mechanical stability and rigidity.

 


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 minutes.

All Harmonics Available
All harmonic options — 532nm, 355nm, 266nm and 213nm — are available as standard.
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 ambient temperature.

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
