Del Mar Photonics presents new unique fully computerized powerful laser
spectrometer for research studies demanding fine resolution and high spectral
density of radiation within UV-VIS-NIR spectral domains.
This fully automated high-resolution spectrometer based on Tekhnoscan's CW narrow-line Ti:Sapphire laser, model TIS-FD-08/A-scan, comes as a perfect embodiment of modern ideas and technology innovation in the field of smart laser spectrometers. Novel advanced design of the fundamental laser component implements efficient intra-cavity frequency doubling as well as provides a state-of-the-art combined ultra-wide-tunable Ti:Sapphire & Dye laser covering a super-broad spectral range between 275 and 1100 nm.
The spectrometer includes, as its base, a CW ultra-wide-tunable narrow-line laser, high-precision wavelength meter, an electronic control unit driven through USB interface as well as a software package. Positions of wavelength selection components in the laser as well as the position of the non-linear crystal are precisely controlled with the help of a closed-loop feed-back system including a wavelength meter. The spectrometer is fully controllable through a user-friendly computer interface that offers a variety of modes for setting and scanning of the radiation wavelength as well as different modes of data acquisition and recording.
The TIS-FD-08/A-scan features LabWindows™ based software running under Windows™ XP/Vista. For acquisition of experimental data an 8-channel 14-bit ADC is used with quantisation frequency of 3 MHz and channel multiplexing frequency 3 MHz.
The spectrometer is designed for wide-range spectral studies and characterization of quantum semiconductor structures, meta-materials, bio-objects as well as for nano-, bio-technological applications, and quality control.

In single- and multi-component nano-scaled materials for efficient energy harvesting and energy storage, the influences of finite size, shape, hierarchal complexity and a dynamic surface chemical environment on properties extend well beyond the constraints posed by traditional materials-specific property closures of individual material components. In the Mesoscaled Materials Laboratory (MML) we investigate the synthesis and selected properties of single- and multi-component inorganic nanostructured and thin-film materials and devices. We are currently investigating:
functional properties of ferroelectric nanostructures and their surface chemical environment, with applicability in memory, sensing, in nanoelectromechanical and photovoltaic energy harvesting, and in other energy-related areas
development of novel synthetic pathways for multi-component nanostructures for electronic and photonic devices
electronic transport in low-dimensional semiconductor and metallic materials and devices, including resonant coupling (and scattering) of electromagnetic radiation with (and by) nanowires
resonant energy transfer between nanostructures, and its applion in proximal scanning probes
the physical properties of selected nano-laminate solids and thin films
