  • Luís Braga defends thesis

    Luís Braga defended successfully his MSc thesis on November 23, being awarded a final grade of 18/20.In his work, Luís evaluates the role of beam collimation at the input of a large aperture, single-pass grating compressor. The experimental setup investigated is the compressor at Vulcan’s laser Target Area West.An analytical model for space-time pulse propagation was developed, which adequately explains the influence of beam collimation on the observed pulse front tilt (PFT). Additionally, a new type of single-shot autocorrelator, capable of measuring pulse duration and PFT independently, was demonstrated.With this, a new mechanism for detecting and controlling the output PFT from a compressor was demonstrated. This work was a successful collaboration between our team at IST and the Vulcan team at the Central Laser Facility, Rutherford Appleton Laboratory.Congratulations to all those involved, especially to Luís!

  • CPA inventors Gérard Mourou and Donna Strickland won the 2018 Nobel Prize in Physics

    The 2018 Nobel Prize in Physics was awarded to Arthur Ashkin for “optical tweezers and their application to biological systems” and to Gérard Mourou and Donna Strickland for “their method of generating high-intensity, ultra-short optical pulses”.  Mourou and Strickland invented  the Chirped Pulse Amplification method (CPA) thirty year ago. The CPA method is used to amplify ultra-short laser pulses (from picosecond to femtosecond). The large spectral width of short pulse lasers is used to enlarge the duration of the pulses in a linear dispersive optical path (stretcher). The pulses become linearly chirped (with larger duration and lower power) and are amplified (gain energy) at a comparable lower intensity (below optical materials damage threshold). After the amplification is concluded the pulse (amplified and chirped) is most of the times moved into a vacuum chamber where a dispersive optical path removes the pulse chirp shortening it to almost its original duration….

  • Rui Silva awarded MSc in Physics Engineering

    Congratulations to Rui Oliveira e Silva for successfully defend his MSc thesis in Physics Engineering!
    In his thesis entitled “Design of optical spectrometers with RamSERS project”, Rui evaluates the parameters for the design of two Raman spectrometers , with the goal of achieving very competitive specifications using off-the-shelf optical elements. The design is verified by paraxial analysis and Zemax.
    The ultimate goal of the project is to develop a portable device for the identification of cancer biomarkers through Raman spectroscopy.
    Well done, Rui!

  • Celso João awarded Best PhD in Optics and Photonics Prize

    Celso João, who successfully defended his PhD thesis in 2016, has now been awarded the Prize for the Best PhD Thesis in Optics by the Portuguese Society for Optics and Photonics (SPOF).
    Celso, a postdoc researcher and member of the Group for Lasers and Plasmas, has specialised in high power laser design and development. In his thesis entitled “Diode-pumped solid-state lasers for optical parametric amplification pumping”, he describes the implementation of new two diode-pumped ytterbium lasers for pumping OPCPA amplifiers.
    The first laser amplifier is installed at IST, while the second was added to the front end of the PHELIX laser at GSI Darmstadt, through a collaboration with IOQ/IAP-FSU Jena. The work was supervised by Prof. Gonçalo Figueira (IST), head of the Laboratory for Intense Lasers in Lisbon.
    SPOF was created in 2009 with the goals of promoting optics from the viewpoints of research, training and education. The national prize for the…
