Del Mar Photonics Bimorph Mirrors

Del Mar Photonics - Adaptive optics (deformable mirrors) - Wavefront sensors - Complete adaptive optics system - Unimorph Deformable Mirrors part numbers

Thickness of the bimorph

For the small mirrors (40mm in diameter) we are typically using 2.5mm thickness.
For 60mm the typical value is 5-6mm and for 100mm it is 8-10mm.

Low or high temperature epoxies used in the bimorph construction

We do not use epoxy, but rather a single component adhesive with activator. The adhesive is thermally stable in the range of -50 +170C.
 

Uncoated mirrors

Bimorf mirrors can be supplied uncoated. However, when you will make a custom coating on the mounted bimorph (unimorph) you should take into account a Curie temperature of piezo ceramic, which is about 190C in our case. When applying a coating we are using coating machine with ion assisting and substrate temperature not exceeding 60-70C.
It's possible to polarize piezo ceramic after the coating, but it’s not a simple procedure.


Surface figure, RMS roughness

As for the surface quality, the best values which we can get are 3-5A (RMS).

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.

UNIMORPH WAVEFRONT CORRECTORS

Del Mar Photonics has adopted and further developed technologies of mirror manufacturing initially proposed in Adaptive Optics Laboratory of Lomonosov Moscow State University. Recent advances in production technology allow us to manufacture a variety of deformable mirrors with 30-60mm aperture diameter, good surface quality, and record stroke for such type of the mirrors. With 30mm aperture, the maximum measured stroke is 50um. Unlike membrane mirrors, this type of wavefront correctors can bear an initial curvature. We have an experience in manufacturing the mirrors with an initial radius of curvature of 500mm. The reflective surface of the mirror can be cleaned by means of a conventional laboratory technique, which facilitates applications in university labs. The mirrors are shock- and vibration-resistant. In comparison with bimorph mirrors, our correctors demonstrate enhanced mechanical stability and better reliability. The mirrors are well-suited for compensation of low order aberrations (up to 4th order of Zernike polynomials).

Principle of operation of unimorph mirrors

The unimorph mirror itself is constructed of a thin plate of piezo-electric material coupled to a substrate plate. The electrode pattern is deposited on the piezo-plate, which is then joined together with the substrate to form a sandwich structure. The ground plane is the back surface of the substrate in the unimorph. An optical surface is formed on the front surface of the substrate plate. The polarization of the piezo-electric plate is chosen so that to make the plate expand or contract when voltage is applied to the electrode. The differential expansion/contraction of the substrate and piezo-plates causes the unimorph to bend, much in the same way as a bi-metallic strip will bend when heated.

	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.

	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.

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
