    King Abdulaziz First Class Medal
    team — The custodian of the Two Holy Mosques King Salman awarded the King Abdulaziz First Class Medal - Saudi Arabia’s highest civilian honor - to Prof. Dr. Abdallah Azzeer, the director of Attosecond Science laboratory (ASL) at King Saud University (KSU). The minister of education delivered the medal in presence of Saudi university rectorsThe medal was awarded to Prof. Dr. Azzeer for his distinctive role in establishing a successful research collaboration between KSU and Max Planck Institute for Quantum Optics (MPQ) and Ludwig Maximilian University (LMU) of Munich. This led to the launching of a new cutting-edge laser …

    Bright attosecond x-ray pulses
    research — Scientists invent a way to see attosecond electron motions with an X-ray laser. The new method will provide sharp views of electrons in chemical processes that take place in a billionths of a billionth of a second and drive crucial aspects of life.

    Honorary membership for Prof. Krausz
    team — Prof. Ferenc Krausz has recieved the honorary membership of the Roland Eötvös Physical Society, Budapest. After receiving the membership the laser physicist of the Ludwig-Maximilians University München and the Max-Planck-Institute of Quantum Optics held an lecture about how attosecond science technologies can in the future contribute to a new way of finding molecules in human biofluids like blood. This may path the way for medical applications to detect diseases by analyzing so called molecular fingerprints with the help of strong laser light pulses.

    Field-resolved infrared spectroscopy of biological systems
    research — In cooperation between the Laboratory of Attosecond Physics at the Max Planck Institute of Quantum Optics and the Centre for Advanced Laser Applications of the Ludwig-Maximilians-Universität München, the King Saud University Riad and the Center for Molecular Fingerprinting (Budapest, Hungary), we have developed a molecular spectroscopy technique that overcomes long-standing limitations of traditional techniques, like Fourier-transform infrared spectroscopy. A powerful femtosecond laser delivers 28 million pulses per second, with highly repeatable waveforms, comprising merely a few infrared-electric-field oscillations. …

    Unfazed by phase shifts
    research — Physicists in the Laboratory for Attosecond Physics at the Max Planck Institute for Quantum Optics (MPQ) and at the Ludwig-Maxmilians-Universität (LMU) Munich have developed a novel type of detector that enables the oscillation profile of light waves to be precisely determined.Light is hard to get a hold on. Light waves propagate with a velocity of almost 300,000 km per second, and the wavefront oscillates several hundred trillion times in that same interval. To work with light, one must control it – and that requires precise knowledge of its behaviour. It may even be necessary to know the exact position of the …

    Nonlinear photoconductive sampling
    research — The electric field of a light wave oscillates so quickly that measuring its exact time dependence is challenging, especially for extremely short light pulses. Until recently, the only reliable technique for such measurements in the visible spectral region was attosecond streaking, which required complex and expensive vacuum equipment. We demonstrate that field-resolved measurements are possible with a simple solid-state device where highly nonlinear photoinjection of charge carriers enables a high temporal resolution, which we refer to as nonlinear photoconductive sampling (NPS). We show that NPS not only reproduces …

    A new laser source for the analysis of molecular fingerprints
    research — Controlling, shaping, and measuring the electric field of light at sub-cycle regime enhances the depth of our insight into microscopic ultrafast dynamics at femtosecond and attosecond time scale. Our developed laser architecture fulfills these criteria.On the one hand, the system allows to generate optimized, non-sinusoidal pulses with scalable peak and average-power for attosecond pulse generation.On the other hand, the system enabled us to detect the electric field of the absorbed light by water molecules at near infrared spectral range for the first time. The demonstrated control and measurement of the electric …

    Fast Lane to the Laser
    team — To ensure that samples of plasma and serum obtained in the course of the Lasers4Life (L4L) project can be stored under optimal conditions, the BIRD Group recently took delivery of an automated refrigeration system designed for use at liquid-nitrogen temperatures. The new Biobank was installed in BIRD’s own laboratory at LEX Photonics, which minimizes the interval between sample recovery and laser analysis. The consignment, which was delivered on six pallets, consisted of the necessary components and peripherals, as well as a workbench specifically designed for the handling of frozen samples in the laboratory. …

    MPG Technology Transfer Grant awarded
    team — The Max Planck Society (Max-Planck Gesellschaft, MPG) has awarded Ioachim Pupeza and his team a »technology transfer« grant, aiming at validating infrared electric-field-resolved spectroscopy (IR-FRS) for gas-phase samples.Our team has pioneered the femtosecond-laser-based technologies underlying high-sensitivity IR-FRS of liquid-phase molecular fingerprinting [1]. The new project aims at the demonstration of the potential of the new spectroscopic technology for gaseous samples. In particular, compared to strongly-absorbing liquids, gases afford orders-of-magnitude longer interaction lengths with the excitation …
