    aseops

    Laser Quantum is launchingthe ASOPS Engine, a next generation time-domain spectrometer! The ASOPS Engine offers extremely fast acquisition speeds: up to 20 kHz and unprecedented time-resolution, significantly below 60 fs for our 1 GHz laser range, and below 100 fs for our 84MHz laser range. The high scan rate, very long measurement windows and high time-resolution are unique features of our ASOPS Engine system, unachievable by conventional measurement techniques.

    The ASOPS Engine consists of two femtosecond lasers, a TL-1000 ASOPS for offset frequency stabilisation, an optical trigger unit, a high-speed balanced optical photoreceiver, a personal computer housing the data acquisition card and the HASSP-Scope software for measurement and analysis of time-domain data.

    The ASOPS Engine is ideal for low-noise ultrafast time domain spectroscopy, high resolution terahertz spectroscopy, two-color pump probe spectroscopy and more. Together with our THz spectroscopy unit the ASOPS Engine can be combined to the HASSP-THz, a versatile and powerful THz-spectrometer that is capable of reaching 100 dB SNR and a high-resolution with short acquisition times.

  • Laser Quantum: Lasers on a Zero-g plane

    zeroG 768x576

    The University of Greifswald recently used a Laser Quantum gem laser laser on a zero-g plane! It had been used as a source for the light sheet analysing dusty plasmons under micro gravity to test a theory.

    The robustness of the laser was a key attribute in undertaking the experiment: The gem, which has recently been the star of the Laser Quantum video’s ‘The gem vs. series’, once again demonstrated its adaptability and durability when working in different environments. It was used in the application of Particle Image Velocimetry (PIV) where dusty plasmons under micro gravity were collected for data, at the time of writing this data is currently being analysed.

    The gem is a compact, high specification, single transverse mode continuous wave laser. Capable of outputting up to 2 W, the gem offers a highly stable, diffraction limited beam that is reliable in many environments. To find out more about the gem laser, please click here.

  • The Laser Quantum torus and its use in Brillouin scattering applications

    Laser Quantum torus

    Read these two papers to find out more about how the Laser Quantum torus laser can be used in Brillouin scattering applications:

    The first paper by G. Scarcelli et. al. demonstrates a label-free microscopy technique of contactless access to biomechanical properties . This technique is based on Brillouin light scattering and the method uses the Laser Quantum torus, a single-longitudinal mode laser. This new method not only makes physical contact obsolete to access these properties, but also increases the resolution onto the order of the wavelength used.

    To read the full paper please click here.

    The second article by J. Zhang et. al, uses Brillouin spectroscopy to determine the mechanical properties of material. This paper looks at parallel detection, where the Brillouin shift of hundreds of points can be measured simultaneously. Parallel detection is a major step forward in bringing this technique towards real world acquisition speeds. Brillouin scattering complements Raman spectroscopy as a label-free spectroscopy technique, also being able to work in e.g. an aqueous environment experiment in which the torus laser is used.

  • Laser Quantum: Ultrafast adiabatic second harmonic generation

    venteon

    Second harmonic generation (SHG) is one of the most fundamental techniques used in the photonics laboratory. Widely used in many applications, such as nonlinear spectroscopy, it can suffer from low conversion efficiency to the higher-energy photon when used with short pulses as these can result in low phase-matching. A team from Tel Aviv University, led by Prof Haim Suchowski, recently reported on the technique of adiabatic frequency conversion using a Laser Quantum venteon OPCPA to generate efficient broadband conversion of ultrashort few-cycle pulses into the visible range.

  • Laser Quantum: The gem vs. world-class production

    Over the past months, Laser Quantum have tested their gem laser under extreme conditions. Away from the laboratory, we have subjected this laser to being driven over by a Range Rover; being dropped from 20 metres; being frozen in a block of ice; being buried in sand and hammered with a wacker plate and being spun in a tumble dryer. The gem has survived every single test. In our final video of the series, we take you behind the scenes of our world-class production facilities to demonstrate the real test processes each of our lasers go through in order to meet our meticulous high standards. It is these high standards which have enabled the gem laser to survive the extreme testing from our previous videos. To gain an insight into our laboratories and our industry-leading testing procedure, watch the gem vs. world-class production now!

  • Laser Quantum torus: Noncontact three-dimensional mapping of intracellular hydromechanical properties by Brillouin microscopy

    torus

    Recent studies by G. Scarcelli et al. detail how the Laser Quantum torus 532 is being used to develop a label free microscopy technique based on Brillouin scattering, capable of imaging intracellular processes with vastly improved optical resolution. Intracellular processes such as the interaction between the liquid and solid phases in the cytoplasm have a critical role in determining how cells deform and move. The most effective way to monitor these processes is in their natural microenvironments, which requires all measurements to be done in situ, hence the need for a label free mapping technique. This approach will enable further understanding of how cells change during ageing, injury healing and disease pathogenesis.

  • Laser Quantum's finesse pure CEP: The only 532nm high power pump laser with direct power modulation for CEP stabilisation

    finesse pure CEP

    Laser Quantum’s finesse pure CEP is the first and only 532nm high power pump laser on the market that provides direct modulation input to its output power. Its patented technology has the ability to receive a phase related error signal from an f-to-2f interferometer into its controller, thereby modulating the output power and hence the carrier envelope phase of a few-cycle laser pulse. Also, the enhanced bandwidth of the finesse pure CEP control loop permits a further reduction of integrated phase noise compared with the more conventional AOM method of phase control, particularly above 10 kHz making it simpler and more cost-effective.

  • Laser Quantum Tera-SED produces intense terahertz radiation after excitation with femtosecond laser pulse

    Laser Quantum Tera-SED

     

    Above: Basic THz generation principle of the Tera-SED emitters. The fs laser radiation (red) comes from the top and excites the GaAs substrate (blue). Every second gap between the + and – electrodes is masked with an isolation layer (green) and gold (yellow) in order to inhibit destructive interference between THz fields emitted from adjacent gaps in the far-field.

    The Laser Quantum Tera-SED is a device emitting intense terahertz (THz) radiation after excitation with a femtosecond (fs) laser pulse. It converts the light from the optical regime into the THz regime with a conversion efficiency of up to 2 x 10-3. The impulsive excitation inherently leads to THz pulses covering a broad spectrum in the frequency regime. The spectrum covers almost two decades from about 100GHz up to 7THz with an intensity peak at 1THz (see figure 1). In this frequency range the electric field of the light is directly measurable in amplitude and phase which is important for a large variety of scientific and technological applications.
