Del Mar Photonics
Computer-controlled high resolution SPECTROMETER based on
broadly tunable CW laser model TIS-FD-08/A-scan
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
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.
Laser Spectrometer Specifications
CW single-frequency ring Dye laser DYE-SF-077 -
Frequency-stabilized CW single-frequency ring Dye laser, model DYE-SF-077, is a further development of model DYE-SF-07. It now includes a system of frequency stabilization on the basis of a thermo-stabilized interferometer and a fast electronic driver.
Laser 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
570-700 nm, output > 1.5 W (10 W pump), linewidth < 100 kHz rms, frequency drift < 30 MHz/hour, smooth scanning 6/20 GHz.
The DYE-SF-077 laser cavity has horizontal orientation, the optical mounts of the cavity elements are attached to a rigid base plate, which is further stabilized by a volumetric framework with three invar rods underneath. Additional passive stability of the position of cavity elements is provided by the vibration isolating design of the laser base.
Dye laser DYE-SF-077 is the first representative of the new generation of dye lasers that offer to the user virtually the same level of convenience and simplicity of operation as with a solid-state tunable laser. As a result we are able to offer an option of combined configuration of DYE-SF-077 with Ti:Sapphire laser.
Laser DYE-SF-077 may be equipped with a USB compatible interface to remotely scan the generation line of the laser and to perform multi-channel data acquisition. Laser DYE-SF-077 also may be shipped together with an atom cell and a system for reduction of long-term generation line drift. Besides, laser DYE-SF-077 in combination with highly-efficient resonant frequency doubler FD-SF-07 delivers several hundreds milliwatts of narrow-band UV radiation within the 285–350-nm range.
